What is a rigid layer that surrounds?
cell wall. A rigid layer of nonliving material that surrounds the cells of plants and some other organisms.
Which is a tough and rigid layer that surrounds plant cells as well as some algae and bacteria cells quizlet?
Cell wall is a tough, rigid layer that surrounds some types of cells. Cell wall is a characteristic feature to cells of plants, bacteria, fungi, algae and some archaea. It is located outside the cell membrane.
What is a rigid layer of nonliving material that surrounds the cells of plants and some other organisms?
Cell Wall – A rigid (non-flexible) layer of non-living material that surrounds the cells of plants and other organisms (bacteria). Cell Wall provides protection, shape and support. Cell Membrane – Forms the outer boundary that separates the cell from its environment.
What is a thin layer that surrounds the nucleus?
A nuclear membrane is a double membrane that encloses the cell nucleus. It serves to separate the chromosomes from the rest of the cell. The nuclear membrane includes an array of small holes or pores that permit the passage of certain materials, such as nucleic acids and proteins, between the nucleus and cytoplasm.
What surrounds the nucleus of a plant cell?
The nuclear envelope surrounds the nucleus and all of its contents. The nuclear envelope is a membrane similar to the cell membrane around the whole cell. There are pores and spaces for RNA and proteins to pass through while the nuclear envelope keeps all of the chromatin and nucleolus inside.
Which plant part connects the leaf blade to the stem?
petiole
The petiole is a stalk that connects the blade with the leaf base. The blade is the major photosynthetic surface of the plant and appears green and flattened in a plane perpendicular to the stem.
What is the function of peroxisome?
Peroxisomes are organelles that sequester diverse oxidative reactions and play important roles in metabolism, reactive oxygen species detoxification, and signaling. Oxidative pathways housed in peroxisomes include fatty acid β-oxidation, which contributes to embryogenesis, seedling growth, and stomatal opening.
