Learn About Plant Cells - Biology Quiz

Explanation
B is an animal cell (no cell wall or large vacuole)
C has no nucleus, so it is prokaryotic (bacteria)
D is a virus

Explanation
Remember, a plant cell has a Cell Wall on the outside that is rigid and square shaped

Explanation
Arrow C represents the nucleus. The nucleus is a membrane-bound organelle found in eukaryotic cells. It contains the cell's genetic material, which is organized into chromosomes. The nucleus controls the cell's activities and is responsible for storing and transmitting genetic information. It is typically located near the center of the cell and is surrounded by a double membrane called the nuclear envelope.

Explanation
The correct answer is Endoplasmic Reticulum because arrow D is pointing to a structure that has a network-like appearance, which is characteristic of the endoplasmic reticulum. The Golgi apparatus is responsible for modifying, sorting, and packaging proteins, and it has a distinct stacked appearance. Mitochondria are responsible for energy production and have a double membrane structure. The nucleus is the control center of the cell and is usually located in the center, not in the area indicated by arrow D.

Explanation
The correct answer is Chloroplast. Chloroplasts are organelles found in plant cells that are responsible for photosynthesis. They contain chlorophyll, a pigment that absorbs sunlight and converts it into energy. The letter E in the diagram most likely represents the chloroplast because it is typically depicted as a round or oval-shaped structure with internal membranes called thylakoids.

Explanation
Arrow F represents mitochondria. Mitochondria are double-membraned organelles found in eukaryotic cells that are responsible for producing energy in the form of ATP through cellular respiration. They have their own DNA and can replicate independently. The presence of arrow F indicates that the organelle being referred to is involved in energy production, which is a characteristic of mitochondria. Chloroplasts, on the other hand, are responsible for photosynthesis, the nucleus is involved in genetic material storage and regulation, and the Golgi apparatus is involved in protein modification and sorting.

Explanation
Arrow G represents the Golgi Apparatus. The Golgi Apparatus is an organelle found in eukaryotic cells that is responsible for modifying, sorting, and packaging proteins and lipids for transport to their final destinations. It receives proteins and lipids from the endoplasmic reticulum and modifies them by adding sugars, lipids, or phosphate groups. The Golgi Apparatus then packages these modified molecules into vesicles and sends them to various parts of the cell or to the cell membrane for secretion.

Explanation
H represents Vacuole. Vacuoles are membrane-bound organelles found in the cells of plants, fungi, and some protists. They are responsible for storing various substances such as water, ions, nutrients, and waste products. Vacuoles also play a role in maintaining cell turgor pressure, regulating pH levels, and storing pigments in plants.
