Possible explanations:

Growing sections

open and close to allow gas exchange

vascular tissue for movement from roots to leaves

vascular tissue for movement from leaves to roots

Answers

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.

What kind of cells have a cell wall? what is the purpose of a cell wall?.

Answers

A cell wall is a fairly rigid layer surrounding a cell located outside of the plasma membrane that provides additional support and protection. They are found in bacteria, archaea, fungi, plants, and algae. Animals and most other protists have cell membranes without surrounding cell walls.

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.

Animalia have radial symmetry and Plantae have bilateral symmetry. Animalia have cell walls and Plantae have cell membranes. Animalia are heterotrophs and Plantae are autotrophs.

Answers

Answer:

Animalia are heterotrophs and plantae are autotrophs

Explanation:

Animalia and Plantae are the major kingdoms that share similarities and differences. Animals are heterotrophs, though plants are autotrophs. Thus, option D is correct.

What are animals and plants?

Animals and plants are eukaryotic organisms that share many organelles and similarities. The animals have radial symmetry and cell membranes, whereas the plants exhibit bilateral symmetry and cell walls.

They both differ in being heterotrophs and autotrophs as animals are incapable of producing their own food while plants are autotrophic organisms that produce food through photosynthetic pathways.

Therefore, animals are heterotrophs and plants are autotrophs.

Which surface of the fern is shinier? Why?

Answers

The upper surface of the fern is more shinier than the lower surface.

The light-tolerant side of the leaf is also shiny, and this is because of a thick waxy cuticle. The shade-tolerant side of the leaf also has a cuticle but if we follow it logically, the light-tolerant side of the leaf needs more protection from heat evaporation because it's always being hit by light.

In what order is the cell cycle?

Answers

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).
