Plant Cell Organisation

Question 1

What are plants made of and what do they form

Answer 1

Organs (made of tissues) and form to make organ systems which can perform tasks to survive and grow eg: transporting substances

Question 2

What are the 5 plant tissues and their job

Answer 2

1. Epidermal tissue- covers the whole plant
2. Palisade mesophyll tissue- part of leaf where most photosynthesis takes place
3. Spongy mesophyll tissue- part of the lead and contains big air spaces to allow gases to diffuse in and out
4. Xylem and Phloem- transport things like water, mineral ions and food around the plant
5. Meristem tissue- this is found at the growing tips of shoots and roots and is able to differentiate into lots of different types of plant cell

Question 3

What is the leaf and what 6 types of tissue does it have

Answer 3

Is a plant organ.

1. Epidermal: upper and lower
2. The palisade layer
3. Spongy mesophyll
4. Xylem and phloem
5. Stomata
6. Guard cells

Question 4

What is the job of epidermal tissue

Answer 4

covered with a waxy cuticle, which helps reduce water loss by evaporation
Upper- transparent so that light can pass through it to the palisade layer
Lower- full of stomata

Question 5

What is the job of palisade layer

Answer 5

Has lots of chloroplasts, where photosynthesis takes place, near the top of the leaf where they can get the most light

Question 6

What is the job of xylem and phloem cells

Answer 6

Form a network of vascular bundles, which deliver water and tiger nutrients to the lead and take away the glucose produced by photosynthesis, also help support the structure

Question 7

What is the job of stomata and what is it controlled by

Answer 7

efficient for gas exchange, which lets carbon dioxide diffuse directly into the leaf. Guard cells close the stomata in repossessed to environment conditions
