Question 1

What is the word equation for photosynthesis?

Answer 1

Carbon dioxide + water —–(light)—-> Oxygen + glucose

Question 2

Label the diagram of the leaf found in Abel’s notes section.

Answer 2

Label the diagram of the leaf found in Abel’s notes section.

Question 3

Where does photosynthesis take place?

Answer 3

Chloroplasts

Question 4

What is light energy converted into?

Answer 4

Chemical energy through glucose

Question 5

What pigment is needed to absorb light?

Answer 5

Chlorophyll

Question 6

What are the 3 factors that affect the rate of photosynthesis?

Answer 6

Concentration of Co2, light intensity, water access

Question 7

What is the chemical equation photosynthesis?

Answer 7

6CO2 + 6H20 —-> C6 H12 O6

Question 8

Where do plants get their lights from?

Answer 8

The Sun

Question 9

Where do plants get their CO2 from?

Answer 9

The Air

Question 10

How are palisade cells adapted for photosynthesis?

Answer 10

They are adapted for photosynthesis because they contact a lot of chloroplasts that aid the plant to collect sunlight

Question 11

How guard cells are adapted to allow gas exchange?

Answer 11

They open the stomata to allow gas to diffuse into the leaf. They also have irregular thickening of cell walls that cause the opening of the stoma between them.

Question 12

How are xylem cells are adapted for water transport?

Answer 12

They lose their end walls so the xylem forms a continuous hollow tube.

Question 13

How Phloem sieve cells and companion cells are adapted for the transport of solutes?

Answer 13

Sieve cells have holes in cell wall to allow liquids to flow between cells, that companion cells have many mitochondria for active transport of sucrose.

Question 14

How is energy transferred to the plant for photosynthesis?

Answer 14

Most plants contain a special colored chemical or pigment called chlorophyll that is used in photosynthesis. Chlorophyll is what absorbs the sun’s energy and turns it into chemical energy. Not all the light energy from the sun is absorbed.

Question 15

What type of substance is needed to absorb energy for photosynthesis?

Answer 15

Chlorophyll

Question 16

List some examples of limiting factors for photosynthesis?

Answer 16

Concentration of CO2, light intensity, water supply.

Question 17

What is the definition for rate of reaction?

Answer 17

The speed at which products are formed from reactants in the chemical reaction.

Question 18

What do we call something that prevents the rate of reaction from increasing?

Answer 18

Inhibitor

Question 19

Compare and contrast osmosis and diffusion listing both the similarities and differences between the two.

Answer 19

Diffusion and osmosis are both passive transport processes, which means they do not require any additional energy input to occur. Particles move from a high concentration area to a low concentration area in both diffusion and osmosis.

Question 20

State what is meant by translocation?

Answer 20

The transportation of sucrose from glucose and starch, they pump the sucrose into sieve tube

Question 21

What is the name of the plant tissue responsible for translocation?

Answer 21

Phloem/Epidermis

Question 22

What is a hormone?

Answer 22

Hormones are chemical substances that act like messenger molecules in the body. Hormones are the body’s chemical messengers, sending signals into the bloodstream and tissues. Usually your hormonal and nervous system work in conjunction together, they coordinate a response for what you want to do. Causes changes in how the body works.
