Answer:
false, a cell CANNOt survive
The answer to this one is true
New found evidence that contradicts with their original theory.
The leaf as a photosynthetic organ includes the following cells which contains chloroplasts
--> the palisade mesophyll
--> the spongy mesophyll and
--> the stomatal guard cells
Although all the green parts of a plant can be involved in the photosynthetic activities (with the exception of the root hairs), the leafs are the main organ of photosynthesis. Photosynthesis is the process by which green plants manufacture their food in the presence of sunlight. This takes place in the chloroplasts of these plant. Chloroplasts are structures that contains chlorophyll which traps in energy from the sunlight.
The mesophyll tissues are located between the upper and the lower epidermis of the leaf. The palisade mesophyll, which is found at the upper part, contains numerous chloroplasts and is the main site of photosynthesis in the leaf.
The spongy mesophyll is located at the lower part of the epidermis. They are irregularly arranged with air spaces between them which are linked to the stomatal openings. They also contain chloroplasts.
The stomatal guard cells are a pair of bean-shaped cells which controls the opening and closing of stomata. These cells contains chloroplasts which contributes to the movement of stomata.
Therefore the three different cells of the leaf that contains chloroplasts are the palisade mesophyll, the spongy mesophyll and the stomatal guard cells.

Answer:
1. B
2. C
3. A
Explanation:
1. Most of the carbohydrates in the foods you eat are digested and broken down into glucose before entering the bloodstream. Glucose in the blood is taken up into your body's cells and used to produce a fuel molecule called adenosine triphosphate (ATP) through a series of complex processes known as cellular respiration.
2. Fats are known as being a long term energy source, and the fat on your body is used a "cushioning" for your bones.
3. To break a protein down into its amino acids you will need enzymes. Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur everywhere in life.
