What is a short,underground stem containing stored food

A deer is grazing on some hillside shrubs. It bites into the leaves of one plant and immediately spits it out because it tastes

zysi [14]

Answer: The center vacoule

Explanation:

Vacuoles are membrane-bounded vesicles whose functions vary in different kinds of cells. Mature plant cells generally contain a large central vacuole.

The plant cell central vacuole is a varsatile compartment. It can hold reserve of important organic material such as protein stockpiled and inorganic ions. Many plant cells use their vacuoles as a disposal sites for metabolic by-products that would endanger the cell if the accumulate in the cytosol.

Vacuoles may also help protect the plant against predators by containing compounds that are poisonous or unpalatable to animals.

Which step in the Gram stain is the critical step in differentiating Gram negative cells from Gram positive cells?

rewona [7]

Answer:

The rapid decolorization with ethanol or acetone

and counterstaining with safranin

When a decolorizer such as alcohol or acetone is added, it interacts with the lipids of the cell membrane. A gram-negative cell loses its outer lipopolysaccharide membrane, and the inner peptidoglycan layer is left exposed: when safranin is added they will turn red. Conversely, gram-positives retain the Cristal violet and will color in purple

Match the function with the cell part. Part A1. You will use each term only once. 2. Contains DNA and directs synthesis of RNA 3

EleoNora [17]

Answer:

1. Contains DNA and directs synthesis of RNA B. Nucleus 

2. Photosynthesis - make energy H. Chloroplast

3. Protein synthesis and folding D. Rough ER 

4. ATP production, cellular respiration A. Mitochondria 

5. Transport molecules around cell C. Vesicle 

6. Functions in storage and digestion F. Vacuole

7. Lipid and carbohydrate synthesis  E. Smooth ER 

8. Modifies, sorts, tags, packages, distributes proteins G. Golgi Apparatus

Explanation:

The cell is the functional unit of all living organism, it´s enclosed by a MEMBRANE in animals, or by a CELL WALL in plants and it´s formed by several organelles that are dispersed in the intracellular fluid or CYTOPLASM, positioned along the CYTOSKELETON, which gives structural integrity to the cell. Vacuoles, Chloroplast and Cell wall are found in plant cells. Each organelle has a distinct function within the cell:

Nucleus - Contains DNA and directs the synthesis of RNA.

Chloroplast - Photosynthesis - make energy.

Rough ER - Protein synthesis and folding.

Mitochondria - ATP production, cellular respiration.

Vesicle - Transport molecules around cell.

Vacuole - Functions in storage and digestion.

Smooth ER - Lipid and carbohydrate synthesis.

Golgi Apparatus - Modifies, sorts, tags, packages, distributes proteins.

Why do land breezes and sea breezes occur?

guapka [62]

sea breezes occur in areas where a large body of water is located next to land. 
During the day the land becomes warmer than the water. As warm air rises over the land, cold from over the water moves in to fill the space, thus causing a sea breeze. However, during the night, because water holds heat longer than land, the air over the water is warmer than the air over the land. As the warm air over the water rises, the cold air over the land moves in to take it's place, thus causing a land breeze.
