Answer:
Visible light
Explanation:
Photosynthesis is a unique phenomenon in which plants use sunlight energy, which is a type of electromagnetic radiation, to manufacture their food. During this process, certain pigments in the leaves of plants called CHLOROPHYLL absorbs the blue and red wavelengths of light ranging from 400nm - 700nm.
However, these wavelengths of light (blue and red) that are used during the photosynthetic process are found in the VISIBLE LIGHT PORTION of the electromagnetic spectrum. The visible light is the only part that can be made use of by photosynthetic pigments.

where is the transport vesels found
Answers
Answer:
The xylem transports water and minerals from the roots up the plant stem and into the leaves. In a mature flowering plant or tree, most of the cells that make up the xylem are specialised cells called vessels. Vessels: Lose their end walls so the xylem forms a continuous, hollow tube.
Explanation:
Lab 9: Kingdom Plantae (12 Points) Introduction Plants are defined as multicellular eukaryotes with cell walls made of cellulose. Nearly all of them contain chlorophyll and carry out photosynthesis. Being photoautotrophs, plants can make all their own organic molecules. All they need is energy from light, carbon from carbon dioxide, water, and various elements (like N, P, K, Ca, and Mg). Water can be absorbed into a plant by osmosis, but it can only travel a few cells away from a source. In order to transport water long distances, some groups of plants have specialized tissues (vascular tissue). Plants without vascular tissues must live in wet areas and cannot grow very tall. Consult the plant lecture, slides, and links on Canvas for more information on defining features of plants and groups of plants. Part 1: Comparing major groups of plants Within the plant kingdom, biologists separate plants into four major groups: bryophytes (mosses and llverworts), pteridophytes (ferns), gymnosperms (conifers), and anglosperms (flowering plants). The separations are primarily based on anatomical structures, particularly the ones they use to transport water in their bodies, and on the different ways in which plants reproduce sexually. **What to submit for this activity** Use the information from lectures, the textbook, and any other sources of your choice to fill out the table comparing the four major groups of plants. Submit your completed table as part of what you upload to the Canvas lab assignment for this week. (5 Points) What are one or more examples? Do they have vascular tissue (xylem and phloem)? Which part of the life cycle/generation is more dominant in structure? (Gametophyte or Sporophyte?) What other characteristics can help you identify this group?

Water is a unique compound with properties which are elemental for the existence of life. List six of these properties and how they are essential for the existence of life.
Answers
Here, we are required to list six of the properties of water and how they are essential for the existence of life.
These properties include:
Water is a universal solventWater is highly cohesiveWater is a Substrate for microbial proliferation.Water supports cellular structure.Water has considerable buffering capability.Water is involved in Catabolic and Anabolic reactions.Water as a universal solvent is evident in its extensive capability to dissolve a variety of molecules and consequently transport them has earned it the designation of “universal solvent,” and it is this ability that makes water such an invaluable life-sustaining force. Biologically, water’s role as a solvent helps cells transport and use substances like oxygen or nutrients such as water-soluble vitamins.The cohesive property of water molecules helps plants take up water at their roots. Cohesion also contributes to water’s high boiling point, which is vital in animals body temperature regulation.Water serves as a substrate for Microbial proliferation because microorganisms grow best in high moisture environment.Water supports cellular structure: Water is quite important in biological structures. Water fills cells to help maintain shape and structure. The water inside many cells (including those that make up the human body) creates pressure that opposes external forces, similar to putting air in a balloon thereby creating a cushion.Water has considerable buffering capability: water buffers cells thereby protecting them from the dangerous effects of acids and bases. Highly acidic or basic substances, like bleach or hydrochloric acid, are corrosive to even the most durable biological materials.Water is involved in Catabolic and Anabolic reactions: Water is directly involved in biochemical reactions to build and break down important components of the cell. Photosynthesis, the process in plants that creates sugars for all life forms, requires water. Water also participates in building larger molecules in cells.Read more:

when can we say that manipulation takes place in plants?
a. when a new variety of plant is produce
b. when cross and self-pollination occurs
c. when the stem is cut and the sprouting stem is visible
d. when seeds are germinating
Answers
Option a. when a new variety of plant is produce. Manipulation takes place in plants when intentional genetic changes are made to produce desired traits, such as through selective breeding or genetic engineering.
Control can happen in plants when deliberate hereditary changes are made to deliver wanted characteristics. This can happen through different techniques like specific rearing, hereditary designing, and hybridization.
Particular reproducing includes deliberately rearing plants with wanted attributes to create posterity with those qualities, while hereditary designing includes the immediate control of a life form's DNA to present or upgrade explicit characteristics. Hybridization includes crossing various assortments or species to make another mixture plant with positive attributes.
Conversely, the regular cycles of cross and self-fertilization and seed germination are not viewed as control since they happen normally and are not purposefully prompted by people. Likewise, cutting a stem and making it sprout isn't viewed as control, but instead a characteristic course of plant development and recovery.

In E. coli bacteria, the lac operon contains genes that code for enzymes that break down lactose. Which statement describes when the genes in the lac operon are expressed?
Answers
The genes in the lac operon are expressed when lactose is present and the repressor protein is unable to bind to the operator region.
In E. coli bacteria, the lac operon contains genes that code for enzymes involved in lactose metabolism. The lac operon is a regulatory system that controls the expression of these genes. The expression of the genes in the lac operon is tightly regulated and depends on the presence or absence of lactose and glucose in the environment.When lactose is present, it binds to the repressor protein (lac repressor), causing a conformational change in the repressor. This change prevents the repressor from binding to the operator region of the operon. As a result, RNA polymerase can bind to the promoter region and transcribe the genes, leading to the production of the enzymes that break down lactose.In the absence of lactose, the repressor protein binds to the operator region and blocks RNA polymerase from initiating transcription. This prevents the expression of the genes in the lac operon.For more questions on protein

Explain how starch can be changed into glucose.iii. Which food type in the list is a long-term energy store? Name one place in the body where it is stored.iv. Explain why pasta can be described as a healthy food.
Answers
i. Fat, protein and carbohydrates are sources of energy, so it can be two of any of them. For now, let's say protein and carbohydrate. (But fat supply energy too, only in long term).
ii. Starch starts being transformed into sugar in the mouth, where the saliva has an enzyme called amylase that will break the starch into glucose molecules. This is the enzyme responsible for this process, it is present in saliva and it also can be produced by the pancreas.
iii. The fat is a long-term energy store, and itf can be found in different compartments of the body, but mainly under the skin and around the internal organs (abdominal and visceral compartments).
iv. Pasta is a healthy food because, as the label shows, it can provide you with lots of energy as it has high values of carbohydrates and proteins, but it has low levels of fats (which can be a good source of long-term stored energy but it can also accumulate in places such as arteries and veins, causing serious damage to your health).

The stems and the roots are both transportation systems, moving different things the plant needs. However, the roots actually get water and essential nutrients out of the soil, while the stems just deliver these things to where they are needed.
What is function of root?One of the most significant ways that roots support life is through this. Through the tree's root system and into the stem, water and minerals are immediately absorbed from the soil and delivered to the leaves, blooms, fruits, etc.
During the colder, dormant months, it is particularly crucial for plants and trees to store nutrients and food. This storage is essential to living through seasons of the year when nutrients are scarce.
The roots' major role also includes anchoring the plant to the ground.
