Plant nutrition pt. 1 worksheet Gr11

Define the term photosynthesis

The process by which light energy is converted into chemical energy in the form of organic molecules

Name the mineral needed to form the cell wall

Calcium

Name two minerals that are needed to make protein

Sulfur and potassium

Name two minerals that are needed to make Chlorophyll

Magnesium and iron

Why is food transported as sugar not a starch?

Because starch is less reactive than sugar sugar is small and soluble, allowing it to dissolve

State and explain three ways in which leaves are structurally adapted for photosynthesis

Waxing cuticle leaves - reduces water loss by evaporation

large surface area - Allows plan to receive maximum sunlight and carbon dioxide

thin-ness of leaves - reduces the distance gases must travel across the leaf for diffusion

What is the widest part of the leaf?

Lamina

Photosynthesis produces carbohydrates names, the carbohydrate that applies to each of the following statements:

Used by plant cells for cellular respiration

Transported influence vessel

Stored in plant cells

Combined with minerals to make organic substances

glucose

Sucrose

Starch

Glucose

Give the chemical formula for glucose

C6 H12 O6

What structure of the plant synthesizes chlorophyll

Chloroplasts

What is the source of carbon dioxide?

The air

Why is light needed for photosynthesis

To start its chemical reactions and also to provide energy to split water molecules into hydrogen and oxygen

This structure prevents the plant from dying out

The cuticle and stoma

This part of the plant allows oxygen to enter and carbon dioxide to leave

Stoma

There’s part of the plant is where most photosynthesis occur occurs

Palisade mesophyll Layer

This part of the plan is responsible for transporting substances to and from the leaf

Xylem and Phloem

Contains air spaces for circulation of gases

Spongy mesophyll Layer and stoma

These parts of the plant has Structures who sell contain chloroplast

Palisade mesophyll Layer, guard cell, spongy mesophyll Layer

layers who is cells do not contain chloroplasts

Upper epidermis and lower epidermis

Give two structural differences between the cells in spongy mesophyll Layer and palisade mesophyll Layer

1. The spongy layer is loose with large spaces and Palisade layer is packed tightly

2. There are more glass in the palisade layer than in the spongy layer
