Biology- Features Of Cells Flashcards
What cell do you find chloroplasts, cell walls and a permanent vacuole.
Plant cell
What are ribosomes?
This process is called protein synthesis. Protein synthesis is very important to cells, therefore large numbers of ribosomes are found in cells. Ribosomes float freely in the cytoplasm
What are differences between eukaryotic and prokaryotic cells
Eukaryotes have a nucleus, where a prokaryotic cell doesn’t. Eukaryotes have complex cell structures whereas prokaryotic is simple. Eukaryotic have linear DNA and prokaryotic shave circular DNA
What is the function of a cell walls in plant cells.
The plant cell wall is composed of cellulose.
Its function is The cell wall of plants maintains the shape of plant cells, supports and strengthens plants, resists water pressure, controls cell growth, regulates metabolic processes for the plant, acts as a physical barrier for the plant, stores carbohydrates and helps with cell to cell signaling.
What are vacuoles made off
These membrane-bound structures are basically just enclosed compartments thatare filled with both inorganic and organic molecules, along with water to support the organelle
What is the function of vacuoles.
Typically, their job includes isolating harmful materials, storing waste products, storing valuable water in a plant cell, helping maintain the pressure within a cell, balancing the pH of a cell, exporting products out of the cell, and storing proteins for seed germination.
What is the function of cytoplasm.
Cytoplasm is responsible for giving a cell its shape. It helps to fill out the cell and keeps organelles in their place. Without cytoplasm, the cell would be deflated and materials would not be able to pass easily from one organelle to another.
Most of the important activities of the cell occur in the cytoplasm. Cytoplasm contains molecules such as enzymes which are responsible for breaking down waste and also aid in metabolic activity.
What is cytoplasm made off.
It is made up of mostly water and salt.
What is the function of a nucleus.
The nucleus maintains the security of the genes and controls the functions of the entire cell by regulating gene expression. This is why the nucleus is sometimes referred to as the control center, or the “brain,” of the cell.
What controls cell multiplication
Nucleus, splits itself in half.
