Photosynthesis

Why do seeds grow temporarily without light?

They are living off the stored food in the seed. Once the stored food is gone, the seed/plant will not continue to grow unless it can perform photosynthesis.

How do gases enter and exit a plant?

They enter and leave through the stomata

Plants are producers.

True

Some plants such as carrots store food in a root to support the next season's growth.

True

Sugars produced by photosynthesis are used to provide energy to make other Carbohydrates, proteins, and fats.

True

Sugars produced by photosynthesis are used to provide energy to make other carbohydrates, proteins and fats.

True

How does water enter a plant?

Water is absorbed through the roots with specialized root cells

What are the reactants and products of photosynthesis?

Reactant- Products- Carbon dioxide & Water Glucose & Oxygen

What specialized tissues transport the water throughout the plant?

Conductive Tissue

Where is chlorophyll located in a plant?

In the cell chloroplasts found in the leaves of the plant

Do aquatic plants produce their own food through photosynthesis?

Yes!

A germinating seed shrivels as the growing seedling uses its stored food.

True

Animals can obtain energy and useful materials by consuming plant and plant parts.

True

Aquatic plants go through photosynthesis.

True

What is the job of a potato in a potato plant?

Stored food for energy use at a later time.

What is the basic food made by a plant during photosynthesis?

Sugar-glucose

What is the ultimate energy source for the process of photosynthesis?

The sun

What do plants do with the extra glucose that they produce?

They use it to produce carbohydrates , proteins, and fats. These are used as sources of stored energy.

Plants use glucose along with minerals from the soil to form ___________, __________, and ____________.

Carbohydrates, Fats, Proteins

Describe the process of photosynthesis?

Carbon dioxide enters the plant through the stomata. Water enter the roots. Sunlight is absorbed by the chlorophyll. The energy from the sunlight chemically combines the carbon dioxide and water to form sugar and oxygen. The plant uses the sugar for its life processes. the oxygen is released through the stomata.

*Some plants produce a high level of carbohydrates such as potatoes, corn, wheat, maple trees, and beet sugar. *Some plants produce a high level of fats such as avocado, olives, peanuts and palm nuts. *Some plants produce a high level of protein such as beans, quinoa and tree nuts. List each as an example of a high level source of carbohydrates, proteins, or fats?

Corn- Carbs Beans- Carbs And Protein Sunflower Seeds- Fats and Oils Wheat- Carbs Maple Syrup- Carbs Sugar Beet- Carbs Olives- Fats and Oils Potatoes- Carbs

*True or False* Plants obtain their energy directly from the sun rather than using light energy to produce food.

False

Plants make food to be used by only animals. (The plant does not use the food.)

False

Plants use heat from the sun as a source of energy for photosynthesis.

False

Sunlight is a food.

False

What does chlorophyll do?

It absorbs sunlight for photosynthesis

Photosynthesis is the conversion of __________ energy into ___________ energy.

Light Chemical

Without light, can a plant produce carbohydrates, proteins, and fats?

No!

What are 2 types of carbohydrates?

Simple sugars & and starches
