Many cells in the body use exocytosis to release enzymes or other proteins that act on other parts of the body or to release molecules that helps cells to communicate with each other.

Why are endocytosis and exocytosis important processes cells?
Sometimes a material is too large to cross the membrane. Cells can use energy to transport these materials in vesicles. A cell uses ENDOCYSTOSI to take in large material or liquids. EXOCYTOSIS is the opposite of endocytosis. It is the process that moves substances that need to be removed. The vesicle then goes to the cell membrane, fuses with it and lets go of the content .
Why do plants cells have choroplast and animal cell do not have them?
Plant cells have chloroplasts because they undergo photosynthesis, which is the process of converting sunlight into energy. Chloroplasts contain chlorophyll, which is necessary for capturing sunlight. Animal cells do not undergo photosynthesis; therefore, they do not need chloroplasts.
What processes do all cells undergo?
First they need to ingest energy in the form of foodstuffs. Then they need to produce the enzymatic facilities that all cells need to GROW; and finally when Growth is sufficient, they must needs to undergo cell division. Repeat as regulated.
Why do plant cells need energy from the sun?
Plants need energy from the sun for food, they do this through photosynthesis which is the cells of the leaves (palisade cells, and inside those, chloroplasts), gathering the suns energy and changing it into glucose. the plant can then use this glucose for food. :)
Can red blood cells also become hard as a bone cell?
No, red blood cells need for ability to fold to squeeze through the narrowest capillaries.
Cells that are active in exocytosis would likely contain many?
If a cell is very active, it would need to have a large number of Mitochondria.

What type of transport does not require energy?
passive transport does not need energy. And two types of passive tansport are osmosis and diffusion
What functions do endocytosis and exocytosis carry out for the cells?
Sometimes a material is too large to cross the membrane. Cells can use energy to transport these materials in vesicles. A cell uses ENDOCYSTOSI to take in large material or liquids. EXOCYTOSIS is the opposite of endocytosis. It is the process that moves substances that need to be removed. The vesicle then goes to the cell membrane, fuses with it and lets go of the content .
Does exocytosis need to expend energy to perform?
Yes , Exocytosis is a part of active transport meaning it needs energy to move from concentration gradients.
Why is it important that sex cells do not go through mitosis?
sex cells need to go through meiosis because the daughter cells will get half the chromosomes. if they when through mitosis they would get all the necessary chromosomes and when an egg is fertilized and creates a child it will have double the number of chromosomes that it needs. it could cause mutations.
How do cells get the oxygen they need for energy production?
through the process of photosynthesis
Why do plants cells have choroplast and animal cell do not have them?
Plant cells have chloroplasts because they undergo photosynthesis, which is the process of converting sunlight into energy. Chloroplasts contain chlorophyll, which is necessary for capturing sunlight. Animal cells do not undergo photosynthesis; therefore, they do not need chloroplasts.
How do cells without mitochondria get energy?
Through anaerobic respiration.It does not need oxygen
Identify which of the following would be composed of cells?
I need help
Which of your cells would yo expect to have more mitochondria?
I would say muscle cells and sperm cells. The mitochondria is the power house of the cell producing the energy need for the cells. Our muscles use up a lot of energy doing everyday activities and sperm cells need the energy for the movement of its flagella.
Why do blood cells need oxygen?
Blood cells need oxygen to move and reproduce, without it, they would die. And in time, you would also die.
