QUIZ - Parts of a Leaf, Chloroplast and Light

How do plants absorb water for photosynthesis?

Through the roots

How do plants absorb carbon dioxide?

through the leaves

How do plants get energy to do photosynthesis?

From sunlight

What absorbs light energy for photosynthesis?

Chlorophyll

What are the ingredients of photosynthesis?

Water and carbon dioxide

What are the products of photosynthesis?

Glucose and oxygen

What is the process of photosynthesis?

Plants use light energy to transform water and carbon dioxide into glucose and oxygen

What is the equation to photosynthesis?

What element makes up carbon dioxide?

Carbon and oxygen

What elements make up glucose?

Carbon, Hydrogyn, and oxygen

Autotroph/producer

Can make there own food using energy from sunlight

Heterotroph/consumer

Get energy by consuming other organisms

Where does photosynthesis occur?

The leafs

What are the parts of the leaf?

Cuticle: The outer surface of a leaf has a thin waxy coating that helps prevent water loss

Epidermis: Cells located below the cuticle protects internal tissues, control water loss, and regulate gas exchange

Stoma: Pores in the leaf to let in carbon dioxide and let out oxygen

Guard cells: Located around the stoma; open and close the stoma for gas exchange

Mesophyll cells: Located near the surface of the leaf and contain lots of chloroplasts it converts light energy into chemical energy

Palisade mesophyll: Contains most of the chloroplasts collum chaped below the upper epidermis

Spongy mesophyll: Irregular-shaped cells located closer to the lower epidermis

The order of parts of the leaf

Upper cuticle, upper epidermis, palisade mesophyll, vein, spongy mesophyll, lower epidermis, guard cells and stroma, lower cuticle

Which to tissues are found in the vein?

Xylem and phloem

What does the word mesophyll mean

middle leaf

What two layers of the plant contain chloroplasts?

Paliside and spongy

What is the outermost layer of cells?

Epidermis

What is the waxy covering of the leaf?

Cuticle

What cells open and close the stomata?

Guard cells

What are the column like cells that lie just under the epidermis?

Palisade mesophyll

What is a opening that allowed for gas exchange?

Stoma

Which layer of cells does photosynthesis occur?

Cytoplasm

What are 3 differences between the cells of the palisade mesophyll and the cells that make up the other areas of the leaf?

Shape,chloroplast density, and how packed they are

What is inside the mesophyll cell?

The chloroplast

Parts of a chloroplast

Thylakoid space: gel filled space inside the thylakoid sac

Stroma: gel filled space inside the chloroplast surrounding thylakoid sac

Thylakoids: Sac like photosynthetic membranes inside the chloroplast

Cytoplasm: gel filled space outside chloroplast but inside the cell membrane

Granum: Stack of thylakoids

Where is the chlorophyll?

In the membranes of thylakoids

What types of cells contain chloroplasts?

Plant cells and algae

What is the energy autotrophs use to make their own food?

Turn sunlight into chemical energy

What simple sugar is produced?

Glucose

Where are most photosynthetic cells in plants found?

The mesophyll

How many chloroplasts can be found in photosynthetic cells?

Thousands

How many membranes surround a chloroplast?
