Chapter 27.1- Photosynthesis on land

Question 1

What is one of the biggest hazard to land photosynthesis organisms?

Answer 1

Desiccation which is excessive water loss.

Question 2

What are some of the features that land plants share with green algae?

Answer 2

• they both come from viridiplantae group of the Archaeplastidas
• all plants in this group have the formation of an embryo
• Both have chlorophyll a and b , vacuole, a cellulose cell wall with turgor pressure

Question 3

What are the ways that algae and land plants differ?

Answer 3

• algae can be unicellular or multicellular, land plants are just multicellular

Question 4

What are bryophytes?

Answer 4

• they are plants that rely on surface moisture for hydration and can withstand dry periods
• they do not have plant roots
• they have a high SA: Ratio
• They rely on diffusion and bulk flow

Question 5

How does the way uptake water risks bryophytes ?

Answer 5

• the way they take in water relies heavily on their environment.
• when they aren’t able to get water, they lose the to perform photosynthesis

Question 6

Ways in which vascular plants differ from bryophytes?

Answer 6

1. Vascular plants do not rely on diffusion to distribute materials internally
2. Larger in cell size
3. transport water through bulk flow
4. absorb water from the roots of plants

Question 7

What are the four major groups of vascular plants?

Answer 7

Lycophytes:
fern and horsetails:
Gymnosperm:
Angiosperms:

Question 8

Structural components of vascular plants:

Answer 8

leaves, reproductive organs, stems, and roots

Question 9

What is the shoot component of vascular plants?

Answer 9

Reproductive cell, Leaf, and stem

Question 10

What is the epidermis tissue of vascular plant cells?

Answer 10

• An outer layer of cells and forms the interface between the plant and the external environment
• provide protection to plants
• enhance the uptake of water

Question 11

What is the vascular tissue of plant cells? And describe both types ?

Answer 11

• fluids get transported from root to leaves or leaves to root
  xylem: transport water
  phloem: transport carbohydrates

Question 12

Ground tissue

Answer 12

is the remaining amount of cells

Question 13

Parenchyma

Answer 13

thin-walled cells that are capable of further division and
differentiation.
