Plant Cell Parts Flashcards
(starch storage organelle)- an organelle in some plant cells that stores starch. Amyloplasts
are found in starchy plants like tubers and fruits.
amyloplast
most plant cells are squarish or rectangular in shape.
Shape
the thin layer of protein and fat that surrounds the cell, but is inside the cell wall.
The ——- is semipermeable, allowing some substances to pass into the cell and blocking
others.
cell membrane
a thick, rigid membrane that surrounds a plant cell. This layer of cellulose fiber gives the cell most of its support and structure. The cell wall also bonds with other cell walls to form the structure of the plant.
cell wall
an elongated or disc-shaped organelle containing chlorophyll. Photosynthesis (in which energy from sunlight is converted into chemical energy - food) takes place in the ———-.
chloroplasts
is a molecule that can use light energy from sunlight to turn water and
carbon dioxide gas into glucose and oxygen (i.e. photosynthesis). ——— is green.
Chlorophyll
the jellylike material outside the cell nucleus in which the organelles are located.
cytoplasm
a flattened, layered, sac-like organelle that
looks like a stack of pancakes and is located near the nucleus. The ——— modifies, processes and packages proteins, lipids and carbohydrates into membrane-bound vesicles for “export” from the cell.
Golgi body
spherical to rod-shaped organelles with a double membrane. The inner membrane is infolded many times, forming a series of projections (called cristae). The ———- converts the energy stored in glucose into ATP (adenosine triphosphate), a high energy molecule, for use by cell.
Mitochondrion
the membrane that surrounds the nucleus.
Nuclear membrane
an organelle within the nucleus. Ribosomal RNA is produced here, then exported into the cytoplasm where it forms the ribosomes.
Nucleolus
The nucleus is a spherical body surrounded by the nuclear membrane. It contains mostly DNA in chromosomes. The nucleus controls many of the functions of the cell (by controlling protein
synthesis). The nucleolus is found within the nucleus.
Nucleus
small organelles composed of RNA. Are sites of protein synthesis.
Ribosomes
a vast system of interconnected, membranous, infolded
and convoluted sacks that are located in the cell’s cytoplasm (the ——- is continuous with the outer nuclear membrane). ——– is covered with ribosomes that give it a rough appearance. ——— transport materials and produces proteins (which are sent to the Golgi body, or inserted into the cell
membrane).
rough endoplasmic reticulum - (rough ER)
a vast system of interconnected, membranous, infolded and convoluted tubes that are located in the cell’s cytoplasm (the —– is continuous with the
outer nuclear membrane). It produces lipids (fats) and membrane proteins; ——- buds off from rough ER, moving the newly-made proteins and lipids to the Golgi body for further processing and to
the membranes.
smooth endoplasmic reticulum - (smooth ER)
