sucrose

Answer 9

sugar found in fruits

Question 10

amino acids

Answer 10

Proteins

Question 11

Parts of a plant cell

Answer 11

Mitochondria, Vacuole, Nucleus, Cell Wall, Cytoplasm, Cell membrane, Chloroplasts

Question 12

Mitochondria

Answer 12

organelle responsible for respiration

Question 13

Vacuole

Answer 13

A space in the plant cell that stores fluid

Question 14

Nucleus

Answer 14

Most important part, is responsible for activity and growth, and has DNA

Question 15

Cell Wall

Answer 15

outer layer of the cell that protects it

Question 16

Cytoplasm

Answer 16

a gelatinous liquid that fills up the plant cell

Question 17

Cell membrane

Answer 17

Is responsible for controlling what substances exit and enter the cell

Question 18

Chloroplast

Answer 18

an organelle that contains chlorophyll, which is where photosynthesis derives from

Question 19

Parts of a leaf cell

Answer 19

Waxy cuticle, upper epidermis, vascular bundle, guard cells, stomata, air spaces, palisade mesophyll, spongy mesophyll

Question 20

Waxy cuticle

Answer 20

A waterproof layer that protects the leaf

Question 21

Vascular bundle

Answer 21

A combination of the phloem (brings sugar/glucose up the plant) and the xylem (brings water and minerals to the leaf

Question 22

Guard cells

Answer 22

Cells that control the opening and closing of the stomata

Question 23

Air spaces

Answer 23

Large gaps between cells that are filled with air

Question 24

Spongy Mesophyll

Answer 24

Allows interchange of gases such as CO2 that are needed for photosynthesis

Question 25

Palisade Mesophyll

Answer 25

Where most of the photosynthesis occurs, contains many chloroplasts that are close for light absorption

Question 26

Upper epidermis

Answer 26

Conserves water by eliminating excess sunlight

Question 27

Lower epidermis

Answer 27

Gas exchange

Question 28

Organelles with the most chloroplasts

Answer 28

Palisade mesophyll, guard cells and spongy mesophyll (rest have no chloroplasts)

Question 29

Xerophytes

Answer 29

A plant that can live with very little water

Question 30

Halophytes

Answer 30

A salt-tolerant plant that can live in waters with high-salinity

Question 31

How water leaves the plant

Answer 31

via diffusion

Question 32

What happens when water is removed from a plant

Answer 32

Vacuole shrink, cells plasmolyse, membrane pulls away from the cell wall

Question 33

How does plasmolyzation happen?

Answer 33

When a cell is placed into a solution with not enough water

Question 34

Solvent

Answer 34

a substances that dissolves solutes, e.g. water

Question 35

Solute

Answer 35

a substance that is dissolved in a solvent e.g. sugar, salt

Question 36

Osmolarity

Answer 36

Water moves from ares of high concentration to areas of low concentration to balance the salt and water ratio

Question 37

Isotonic

Answer 37

equal ratio of solvent to solute, leads to flaccid cell

Question 38

Hypertonic

Answer 38

unbalanced ratio with more solute (salt), leads to plasmolysed cell

Question 39

Hypotonic

Answer 39

unbalanced ratio with more solvent (water), leads to turgid cell

Question 40

What is nitrogen needed in the plant for

Answer 40

is needed to ensure energy is available when needed is also a key part in amino acids which provides proteins and enzymes for plants

Question 41

What happens to a nitrogen deficient plant

Answer 41

Plant turns yellowish - green, growth slows, reduced tiller development

Question 42

What is phosphorus need in the plant for

Answer 42

Harvests the sun's energy and turns it into growth and reproduction, also used to make DNA, cell membranes, respiration and growth

Question 43

What happens to a phosphorus deficient plant

Answer 43

Leaves turn dark, dull, blue-green and maybe pale is severe cases, problematic growth

Question 44

What is potassium needed for in the plant

Answer 44

needed for movement of water, nutrients, and carbs, is involved with enzyme activation, produces ATP. Helps enzymes in photosynthesis and respiration

Question 45

What happens to a potassium deficient plant

Answer 45

Plant wilts on dry, sunny days and normally wilts, also has brown scorching and curling leaf tips as well as chlorosis - yellowing between leaf veins, poor flower and fruit growth

Question 46

What is magnesium needed for in the plant

Answer 46

Magnesium is the central core of chlorophyll molecule, it also helps activate some enzyme and gives vibrant green color to enable photosynthesis

Question 47

What happens to a magnesium deficient plant

Answer 47

Yellow between leaf veins, with sometimes reddish brown tints, early leaf fall, photosynthesis won't be able to happen
