Why is it ecologically relevant for plants to have their seeds dispersed.
Answer:
Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources
Explanation:
Plants allows gas exchange and many other functions to help the ecosystem. Correctly
match the words on the with the explanations.
Words:
Guard Cells
meristematic tissue
root hairs
xylem
Phloem
Possible explanations:
Growing sections
increases surface area for water absorption
open and close to allow gas exchange
vascular tissue for movement from roots to leaves
vascular tissue for movement from leaves to roots
Answer:
xylem → vascular tissue for movement from roots to leaves
phloem → vascular tissue for movement from leaves to roots
Root Hair → increases surface area for water absorption
Meristematic tissue → Growing Sections
Guard Cells → open and close to allow gas exchange
Explanation:
The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots.
Root hairs increase the surface area for the absorption of water and minerals from the soil.
Meristem is the name of the specific area where plant growth occurs.
Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata.

In what order is the cell cycle?
Answer:
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
Answer:
THE CELL CYCLE:
-increases in size (gap 1, or G1, stage)
-copies its DNA (synthesis, or S, stage)
-prepares to divide (gap 2, or G2, stage)
-divides (mitosis, or M, stage).

What kind of cells have a cell wall? what is the purpose of a cell wall?.
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.

D. Chloroplast
Some body please help me fast
Answer:
B. ERExplanation:
is just my opinionbut hope it helps youAnswer:
[A] Cell Wall
[B] ER
[D] Chloroplast
Explanation:
The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the plant cell.
The ER is the production, processing, and transport of proteins and lipids.
Chloroplasts enable the conversion of light energy into the chemical form without which the plants would be unable to perform photosynthesis.

Soil that has little to no permeability
is at risk of becoming
A. nutrient-dense
B. salty
C. water logged
Soil with low permeability is prone to becoming waterlogged. Thus, correct option is C.
The ability of soil to transport air and water is referred to as permeability. Water has a difficult time penetrating or draining through soil that has little to no permeability, which causes poor drainage and water buildup. This condition may lead to soggy soil, where excess water is unable to evaporate and depletes the soil's oxygen reserves.
The growth and health of plant roots are harmed by this. In oxygen-deficient conditions, microbial activity declines, which reduces the availability of nutrients. Although salt accumulation may happen in arid areas, it is not a direct result of limited permeability. Therefore, option C, water logged soil, is the proper response.

why does climate change as you move from the equator to the north and South Pole
Answer:
Temperature range increases with distance from the equator. Also, temperatures decrease as you move away from the equator. This is because the suns rays are dispersed over a larger area of land as you move away from the equator. This is due to the curved surface of the earth.
