A cell is a highly organized unit with many internal components or organelles, like the nucleus, mitochondria and endoplasmic reticulum. These structures perform specialized tasks such as energy production, protein synthesis and waste removal. Though it may look like a bag of liquid, the cytoplasm holds a complex network of life processes that make the cell a dynamic and functional unit.

Mitochondria, often called the powerhouses of the cell, produce energy by converting glucose and oxygen into ATP through cellular respiration. Their presence in animal cells indicates the high energy demands of these cells. From movement to growth, energy is vital and mitochondria supply this by efficiently managing cellular metabolism, keeping the cell alive and functioning properly.

Plastids are specialized structures in plant cells involved in storage and food production. The most important plastid, the chloroplast, contains chlorophyll, a green pigment that captures sunlight. Chloroplasts use sunlight, water and carbon dioxide to perform photosynthesis, producing food for the plant. This process not only supports the plant but also contributes oxygen to the environment, making chloroplasts vital for life on Earth.

Plant cells are considered more structured due to their rigid cell walls made of cellulose. This gives them a firm, rectangular shape. The large central vacuole also contributes to the cell’s structure and turgidity. In contrast, animal cells lack a cell wall and have a flexible, irregular shape. ThRead more
Plant cells are considered more structured due to their rigid cell walls made of cellulose. This gives them a firm, rectangular shape. The large central vacuole also contributes to the cell’s structure and turgidity. In contrast, animal cells lack a cell wall and have a flexible, irregular shape. This architectural rigidity in plant cells makes their tissues appear more orderly and defined.

Vacuoles are storage sacs found in plant and animal cells. In plant cells, the central vacuole is large and filled with cell sap—a mix of water, salts and sugars. It helps maintain internal pressure (turgor), keeps the cell rigid and stores nutrients and waste. By supporting the plant’s structure anRead more
Vacuoles are storage sacs found in plant and animal cells. In plant cells, the central vacuole is large and filled with cell sap—a mix of water, salts and sugars. It helps maintain internal pressure (turgor), keeps the cell rigid and stores nutrients and waste. By supporting the plant’s structure and regulating water balance, vacuoles play a key role in plant health and stability.
