2A Plant Cell Organisation

Question 1

what works tog in an organ system that transports substances around the plant

Answer 1

roots stem and leaves

Question 2

what are the examples of plant tissue

Answer 2

epidermal tissue, palissade mesophyll tissue, spongy mesophyll tissue, xylem, phloem, meristem tissue

Question 3

whats the function of epidermal tissue

Answer 3

covers the whole plant

Question 4

whats the function of palisade mesophyll tissue

Answer 4

parts of the leaf where most photosynthesis occurs

Question 5

whats the function of xylem and phloem

Answer 5

transport things like water and mineral ions and food around the plant through roots stem and leaves

Question 6

whats the function of meristem

Answer 6

found at the tip of shoots and roots and are able to differentiate into lots of different types of plants cells, allowing plant to grow

Question 7

hows the epidermal tissue adapted for its function

Answer 7

• covered with waxy cuticle- helps reduce water loss by evaporation
• upper tissue ar tansparent- light can passs to palisade mesophyll layer

Question 8

hows the palisade layer adapted for its func

Answer 8

• lots of chloroplast

- near top of leaf where they get most light

Question 9

hows the xylem and phloem adapted for their func

Answer 9

• form network of vascular bundles- deliver water and other nutrients and take away glucose produced by photosynthesis
• support structure

Question 10

hows the lower epidermal adapted for efficient gas exchange

Answer 10

full of little holes called “stomata”- let co2 diff directly into leaf. The opening and closing of stomata are controlled by guard cells
