cell wall and cell membrane
what is cell wall
a tough, flexible, and sometimes rigid, structural layer surrounding some types of cells, just outside the cell membrane
what is the definition chloroplasts
an organelle within the cells of plants and certain algae that is the site of photosynthesis
what is mitochondria structure
surrounded by a double-membrane system, consisting of inner and outer mitochondrial
what is the definition of a nucleus
the structure in a cell that contains the chromosomes
How does cytoplasm hold a
the internal components of cells in place
what is cell membrane function
provide protection for a cell
where does chloroplasts get there energy from
the sun
what is Ribosome function
the site of protein synthesis in the cell.
what is the function of nucleus
the repository of genetic information and as the cell's control center.
What is cytoplasm made of?
water, salts, and proteins.
what cannot go through cell wall
larger uncharged polar molecules, such as glucose,
why is chloroplast green
it reflects green light
What are mitochondria
membrane-bound cell organelles
what happen if the nucleus does have DNA what will happen.
the cell can't divide and will eventually die.
Which is NOT a function of the cytoplasm?
Provide support
Make proteins
Provide protection
Stores molecules
make proteins
cell membrane mostly made of
phospholipids
what is chloroplast responsible for
photosynthesis
Where are ribosomes synthesized in the cell?
Nucleolus Mitochondria Cytoplasm.
Why does every cell in our body contain DNA?
to carry genes
what is the function of Cytoplasm
holds the internal components of cells in place and protects them from damage.
is cell wall a plant or animal
Describe the function of a chloroplast?
produced energy from photosynthesis and oxygen release processes.
what does mitochondria made of
phospholipid bilayers and proteins
Why don't electrons in the atom enter the nucleus?
only certain special orbits known as discrete orbits of electrons are allowed inside the atom and while revolving in discrete orbits, the electrons do not radiate energy.
what is Cytoplasm structure
a thick solution that fills each cell and is enclosed by the cell membrane.
