Topic 3

Question 1

What are cells and what do they do

Answer 1

They all are special and preform different functions

Question 2

What are Tissues what do they do

Answer 2

a group of specialized cells working together to preform a function

Question 3

What do organs do

Answer 3

are tissues contributing to the same function

Question 4

What is the organ system

Answer 4

a group of organs working together

Question 5

what is a unicellular organism?

Answer 5

All life process is in one cell, a large surface area to volume ratio and has a shorter life than a multicellular organisim

Question 6

What is a multicellular organism?

Answer 6

have different specialized cells that all preform different functions, small surface area to volume ratio and a longer life than the unicellular organisim.

Question 7

Dermal tissue is found where?

Answer 7

on the outsides of plants

Question 8

What does dermal tissue create and what does that do?

Answer 8

A cuticle and a cuticle is a waxy covering that protects the plant from water loss and insect attacks

Question 9

The ground tissue is found where?

Answer 9

Right under the upper epidermis

Question 10

What does the ground tissue do?

Answer 10

is responsible for the photosynthesis plus the water and food resources.

Question 11

why is the palisade tissue compacted together?

Answer 11

Because it allows for better photosynthesis

Question 12

what is the spongy mesophyll tissue do in the ground tissue?

Answer 12

is not compact like the palisade in order to maximize the diffusion of gases.

Question 13

Vascular tissue is used for?

Answer 13

The transportation of materials

Question 14

what are the two tubes that transport the materials?

Answer 14

Phloem and Xylem

Question 15

What does Xylem do?

Answer 15

Moves the water and minerals absorbed from the roots of the plant to the rest of the whole plant

Question 16

What does phloem do?

Answer 16

glucose and sugars from the leaves to the rest of the plant

Question 17

What is a Vascular bundle

Answer 17

Seen as the veins of the leaf on the underside of the leaf

Question 18

Describe what the shoot system does

Answer 18

The shoot system includes tubers, stem, leaves, buds, flower’s and fruits. Containing photosynthesis organs that can absorb Co2 and then release 02

Question 19

Describe what the Root system does

Answer 19

The root system is everything underground the plant, and absorbs the water and minerals from the soil

Question 20

Reactants for Photosynthesis

Answer 20

Carbon dioxide (CO2)
Water (H2O)
Light energy

Question 21

Reactants for Cellular Respiration

Answer 21

Glucose (C6H12O6)
Oxygen (O2)

Question 22

Products of Photosynthesis (what u get from photosynthesis)

Answer 22

Glucose (C6H12O6)
Oxygen (O2)

Question 23

Products of Cellular Respiration (what u get from cellular respiration)

Answer 23

Carbon dioxide (CO2)
Water (H2O)
ATP (energy)

Question 24

Equation for Photosynthesis

Answer 24

Carbon Dioxide + Water –sunlight→ Glucose + Oxygen
​

Question 25

Equation for Cellular Respiration

Answer 25

Glucose + Oxygen → Carbon Dioxide + Water + ATP

Question 26

What does the stomata do?

Answer 26

Stomata does the gas exchange for the plant

Question 27

what are guard cells and what do they do?

Answer 27

Guard cells are specialized cells and protects the stomata from water loss, plus only opening when sunlight hits them and closing when its not

Question 28

How does the stomata close and what happens when it does close?

Answer 28

When the sunlight does not hit the guard cells making them closed the potassium is no longer pumped by active transport and then potassium diffuses back out through the guard cells going along the concentration gradient

Question 29

How does the stomata open and what happens when it does open?

Answer 29

The two guard cells open when the sunlight hits the stomata then potassium is pumped in through the guard cells by active transport and then water from the ECF is flows into the cell by osmosis

Question 30

What are Lenticels

Answer 30

In woody plants allow the entry of gases

Question 31

What is Phototropism

Answer 31

Is the tendency of a plant growing towards the light source

Question 32

Which part of a plant in Phototropism is negative and positive and negative and why?

Answer 32

The stem is positive because the stem can sense the light allowing the stem to grow toward the light. the Roots have a negative phototropism because the roots are underground growing the opposite way of the light source.

Question 33

Auxins function

Answer 33

The substance which allows the plant to have phototropism, and a hormone that produced in plants the transported to cells which can elongate upon its contact.

Question 34

Gravitropism is

Answer 34

Direction of plant growth depending on the response of gravity

Question 35

what on the plant has negative and positive gravitropism

Answer 35

Stems are negative because of a 90 degree angled turn to the left Roots are positive because of a 90 degree angled turn to the right
