Plants use a process called photosynthesis to convert solar energy into food. They use chlorophyll, a pigment found in the chloroplasts of their cells, to capture sunlight and convert it into chemical energy. This energy is then used to combine carbon dioxide and water to produce glucose, which the plant uses as its primary source of nutrition.

Plants use chloroplasts to make food from the sun by a process called photosynthesis. Chloroplasts contain chlorophyll which captures sunlight and converts it into chemical energy that is used to make glucose from carbon dioxide and water.
What organelle is responsible for allowing the passage in and out of the cell-"the gate keeper"?

Chloroplast
Plasma membrane
Mitochondria
Cytoplasm
Plasma membrane is responsible for allowing the passage in and out of the cell. It acts as a gatekeeper of the cell by regulating the movement of substances such as nutrients, waste products, and ions in and out of the cell. The plasma membrane is made up of a phospholipid bilayer and various types of proteins which work together to control the movement of substances.
What is the difference between prokaryote and eukaryote cells?

prokaryote cells are multicellular
eukaryote cells do not have a nucleus
They both have a nucleus
prokaryote cells do not have a nucleus and eukaryote cells do have a nucleus
The main difference between prokaryotic and eukaryotic cells is that prokaryotic cells do not have a nucleus and eukaryotic cells do have a nucleus. Prokaryotic cells are typically smaller and simpler in structure, with no membrane-bound organelles, while eukaryotic cells are larger and more complex, with a variety of membrane-bound organelles such as mitochondria, lysosomes, and endoplasmic reticulum. Prokaryotic cells are typically unicellular, while eukaryotic cells can be unicellular or multicellular.
Why do animal cells have a small vacuole and not a large central vacuole like plant cells?
Animal cells have a small vacuole and not a large central vacuole like plant cells because animal cells have different functions compared to plant cells. While plants use the central vacuole to store water, nutrients, and waste products, animal cells do not need to store large amounts of water or other substances in a vacuole. Instead, animal cells rely on other organelles such as lysosomes to store and recycle waste products, and regulate the cell's internal environment. Additionally, animal cells have a more complex and flexible shape compared to plant cells, which require a smaller vacuole to allow for movement and adaptation to their environment.
