Key insights

• ⭕ Cell membrane, cytoplasm, and nucleus are the common parts of a cell.
• 🔬 Cell membrane is selective permeable, allowing essential materials to enter and removing waste products.
• 👥 Cytoplasm provides cell shape and is the site of cellular functions like protein formation, respiration, mitosis, and meiosis.
• 🧬 Nucleus contains DNA, controls cell activities, and produces ribosomal RNA for protein synthesis.
• 🔄 Ribosomes are responsible for protein synthesis and are floating organelles in the cytoplasm.
• 🔗 Endoplasmic reticulum includes rough and smooth types, responsible for protein formation, lipid production, and detoxification.
• 🔘 Rough endoplasmic reticulum produces proteins with ribosomes, encloses them in vesicles for transport to the Golgi body for modification before export.
• 🔋 Mitochondria is the power station of the cell, responsible for cellular respiration and ATP production; contains its own DNA.

Q&A

• How do animal and plant cells differ in terms of vacuoles?

  Animal and plant cells differ in vacuole size; animal cells have many smaller vacuoles, while plant cells have one large vacuole, which serves as a storehouse of the cell.

• What is the function of lysosomes in a cell?

  Lysosomes are the digestive part of the cell containing enzymes that break down food into simpler forms like glucose and amino acids.

• What is the role of mitochondria in a cell?

  Mitochondria functions as the power station of the cell, responsible for cellular respiration and producing energy in the form of ATP.

• How do proteins move within a cell?

  Proteins are synthesized by ribosomes, transported by endoplasmic reticulum and golgi body, and delivered to targeted destinations by vesicles.

• What are the functions of ribosomes in a cell?

  Ribosomes are responsible for protein synthesis, producing proteins for cell growth and repair.

• What is the role of the nucleus in a cell?

  The nucleus is the control center of the cell, containing DNA, controlling cell activities, and producing ribosomal RNA for protein synthesis.

• What are the three common parts of a cell?

  The three common parts of a cell are the cell membrane, cytoplasm, and nucleus/DNA. The cell membrane is selectively permeable, allowing essential materials to enter and removing waste products. Cytoplasm provides shape to the cell and is the site of many cellular functions like protein formation, respiration, mitosis, and meiosis.

• 00:00 Cells have three common parts: cell membrane, cytoplasm, and nucleus. The cell membrane is selective permeable, allowing essential materials to enter and removing waste products. Cytoplasm provides shape to the cell and is the site of many cellular functions.
• 01:12 The cytoplasm contains essential organelles, while the nucleus is the control center of the cell, containing DNA, controlling cell activities, and producing ribosomal RNA for protein synthesis. Ribosomes are key organelles responsible for protein synthesis.
• 02:24 Ribosomes make proteins for cell growth and repair. Endoplasmic reticulum includes rough and smooth types, responsible for protein formation and lipid production, and detoxification.
• 03:28 The rough endoplasmic reticulum produces proteins with the help of ribosomes, encloses the proteins in vesicles, which are transporters within the cell. These vesicles carry the proteins to the Golgi body, where proteins are modified before being exported.
• 04:31 Proteins are synthesized by ribosomes, transported by endoplasmic reticulum and golgi body, and delivered to targeted destinations by vesicles. Mitochondria functions as the power station of the cell.
• 05:42 Mitochondria contain its own DNA. They are responsible for cellular respiration, producing energy in the form of ATP. Lysosomes are the digestive part of the cell containing enzymes. Vacuoles act as storehouses of the cell. Animal and plant cells differ in terms of vacuole size.
