Essential Components and Functions of Cell Structure

🔬 All cells have a cell membrane, cytoplasm, and DNA.

🧬 Eukaryotic cells have organelles like the nucleus, while prokaryotic cells do not.

🔎 Organelles are specialized parts within cells.

🔑 Organelles are the specialized parts of a cell that have unique jobs to perform.

🧬 The nucleus is the control center of the cell, containing DNA or genetic material.

🧮 Ribosomes, located outside the nucleus, synthesize proteins.

🧠 The cell contains organelles that float in the cytoplasm, including ribosomes and the endoplasmic reticulum.

📦 The endoplasmic reticulum serves as a passageway for transporting materials, such as proteins, in small vesicles.

🏭 The golgi apparatus receives proteins from the endoplasmic reticulum and customizes them for the cell's use.

🔑 Proteins can be modified by adding lipids or carbohydrates.

🔑 Vacuoles store different materials in plant cells.

🔑 Lysosomes break down damaged cell parts using enzymes.

🔑 Mitochondria produce ATP molecules for cell energy.

🔑 Cells with higher energy needs have more mitochondria.

📚 Cells maintain their shape through a cytoskeleton, which includes microfilaments and microtubules.

🌿 Some plant cells have a chloroplast where photosynthesis occurs, and they also have a cell wall for support and protection.

🔬 There are other unique cell structures in different organisms.

🔬 Cells have different structures like cilia and flagella.

🧬 Eukaryotic cells have a nucleus and membrane-enclosed organelles.

🌱🐾 Only the sperm cell in humans has a flagellum.

🔍 All cells have a cell membrane, cytoplasm, and genetic material.

🌿🦠 Only plant cells have chloroplasts, but both plant and animal cells have mitochondria.
