What else can I help you with?
The part of the cell that is in most direct contact with the environment is the?
The cell membrane, which surrounds the cell and is responsible for which molecules are allowed to diffuse into or out of the cell and which molecules are impermeable to the membrane
What structures are used for direct Cell to Cell signalling?
Gap junctions and plasmodesmata are two structures used for direct cell-to-cell signaling in organisms. Gap junctions are found in animal cells, allowing for the transfer of ions and small molecules between adjacent cells, while plasmodesmata are present in plant cells and facilitate the movement of molecules and signals between interconnected cells.
Why dont animal cells have a cell wall?
Before answering this question, it is important to know the function of a cell wall. Cell walls are found in plants to provide rigidity to support the shape of the cell. Animals do not require those functions in cells, hence they do not need cell walls.
What is the pH of a carbolfuchsin direct stain?
The pH of a carbolfuchsin direct stain is typically acidic, around pH 2.5-3.0. This acidic pH helps the stain penetrate bacterial cell walls and bind to the cell structures, making them visible under a microscope.
How do cells respond to contact with other cells?
Cells can respond to contact with other cells through a process called cell-cell communication. This communication can involve direct contact between cell surface molecules or the release of signaling molecules that can bind to receptors on neighboring cells. These interactions can trigger a variety of responses, such as changes in gene expression, cell growth, differentiation, or cell death.
What structures are presents in an animals cell but not plant cell?
it is the organ cell.
What are two structures that plant cell have that animals cell do not?
A cell wall and chloroplasts.
What is the part of the cell that is in most direct contact with the enviorment?
The cell membrane.
What structures are found in an animals cell but not a plant cell?
Animal cells have centrioles.
What cell structures to plant in animals not have in common?
Cell wall, centrioles and chloroplasts
What structures are found in animals cell but not in plants cell?
Animal cells have centrioles.
What structures are present in an animals cell but not in a plant cell?
i think the answer would be centriole
What are two cell structures that are in plants but not animals?
Two cell structures that are unique to plants and not found in animals are chloroplasts, responsible for photosynthesis, and cell walls, providing structural support and protection for plant cells.
What structures are found in animals but not in plant cells?
all structures, excluding chloroplasts and cell walls
What structures are found in plants but not animals?
Some structures found in plants but not animals include chloroplasts (responsible for photosynthesis), cell walls (provide structure and support), and plastids (store food and pigments). Additionally, plants have specialized structures like roots, stems, and leaves for functions such as anchoring, transport, and photosynthesis, which animals lack.
What structures are found in animals cells but not plants cells?
all structures, excluding chloroplasts and cell walls
What structures are found in animals cells but not plant cells?
all structures, excluding chloroplasts and cell walls
