Almost all cells contain organelles, but there are some which do not. Red blood cells do not contain organelles, they only contain hemoglobin.

Yes, certain types of cells contain specific organelles while others do not, based on their function and specialized requirements. For example, animal cells contain mitochondria for energy production, while plant cells contain chloroplasts for photosynthesis. However, all cells have some common organelles, such as the nucleus and cytoplasm.
No, not all animal cells contain the same type and quantity of organelles. Different cells have different functions, so they may contain different organelles depending on what they need to accomplish. Organelles can also vary in quantity depending on the cell's metabolic demands.
Prokaryotic cells, such as bacteria, do not have membrane-bound organelles found in eukaryotic cells. Prokaryotic cells have a simpler structure with a lack of organelles such as a nucleus, mitochondria, and endoplasmic reticulum. They typically have a single circular chromosome and lack membrane-bound organelles.
Yes, all cells contain cytoplasm. Cytoplasm is a jelly-like substance that fills the cell and surrounds the organelles. It plays a crucial role in various cellular functions such as supporting organelles and facilitating cellular processes.
Some important questions to ask about cells include: What is the function of this cell? How does it interact with other cells? What organelles does it contain? How does it reproduce? What is its role in the overall function of the organism?
Cells can vary in size due to factors such as their specific function or stage in the cell cycle. For example, egg cells are larger to accommodate the necessary organelles for development, while red blood cells are smaller for efficient gas exchange. Additionally, some cells may become larger due to an increase in cytoplasmic content or organelles as they grow and mature.
