Plant Cells Flashcards
(15 cards)
What type of organisms are plants classified as?
Eukaryotes
Plants have distinct cellular structures compared to other eukaryotes like animals.
Name a structure that is found in plant cells but not in animal cells.
Chloroplasts
Chloroplasts are essential for photosynthesis.
What is the function of the vacuole in plant cells?
Stores water and other substances
Vacuoles help maintain turgor pressure in plant cells.
What membrane controls the movement of molecules into and out of the vacuole?
Tonoplast membrane
The tonoplast is a specialized membrane surrounding the vacuole.
What structure provides support and protection to plant cells?
Cell wall
The cell wall is primarily made of cellulose.
What are amyloplasts responsible for storing in plant cells?
Starch
Amyloplasts are specialized for starch storage.
What is the role of the middle lamella in plant cells?
Sticks cells together
The middle lamella is a pectin layer that helps in cell adhesion.
What structures allow communication between plant cells?
Plasmodesmata and pits
These structures facilitate the transport of substances and signals.
Fill in the blank: Plant cells have a _______ membrane that regulates vacuole content.
tonoplast
True or False: Plant cells contain centrioles.
False
Centrioles are typically absent in plant cells.
List the key organelles found in plant cells.
- Chloroplasts
- Vacuole
- Cell wall
- Amyloplasts
- Mitochondrion
- Nucleus
These organelles perform specific functions necessary for plant survival.
Compare plant and animal cells regarding chloroplasts and cell walls.
Plant cells have chloroplasts and a cell wall; animal cells do not.
This distinction is crucial for photosynthesis and structural integrity.
What is the function of the Golgi apparatus in plant cells?
Modifies, sorts, and packages proteins
The Golgi apparatus plays a key role in the secretion and delivery of proteins.
What is the primary role of ribosomes in any cell?
Protein synthesis
Ribosomes can be free in the cytoplasm or bound to the endoplasmic reticulum.
Fill in the blank: The _______ is the structure in plant cells that is primarily responsible for photosynthesis.
chloroplast
