Specialised Cells Quiz

Specialised Cells

• Specialised cells are designed for specific functions within an organism.

Red Blood Cells

• Function: Transport oxygen throughout the body.
• Features: Bi-concave shape allows for maximum surface area for gas exchange; lacks a nucleus to accommodate more hemoglobin.

Sperm Cells

• Function: Responsible for fertilizing egg cells.
• Features: Possesses a flagellum (tail) that enables motility towards the egg.

Ciliated Epithelial Cells

• Function: Move mucus out of the respiratory system.
• Features: Abundant mitochondria provide energy; finger-like projections (cilia) help waft mucus upward.

Egg Cell (Ovum)

• Function: Combines with sperm to create a zygote.
• Features: Has a protective slime coat; cell membrane hardens after fertilization to prevent multiple sperm entry.

Palisade Cells

• Function: Conduct photosynthesis in plants.
• Features: Packed with chloroplasts, maximizing light absorption needed for photosynthesis.

Root Hair Cells

• Function: Absorb water and minerals from the soil.
• Features: Elongated shape increases surface area, enhancing absorption efficiency.

Nerve Cells

• Function: Transmit impulses throughout the body.
• Features: Long axon allows for rapid signal transmission over distances.

Key Components of the Digestive System

• The digestive system consists of various organs working in sequence to break down food, absorb nutrients, and expel waste.

Life Process in Locomotor Organ System

• Involves movement and coordination, enabling organisms to navigate their environment.

Function of Vacuole in Plant Cells

• Vacuoles store nutrients, waste products, and help maintain turgor pressure for structural integrity.

Role of Mitochondria

• Mitochondria are the powerhouse of the cell, where ATP (energy) is produced through cellular respiration.

Solids

• Solids do not flow or change shape.
• Solids have a fixed volume that does not change.
• Solids cannot be compressed.

Liquids

• Liquids flow and can change shape.
• Liquids have a fixed volume that does not change.
• Liquids cannot be compressed.

Gases

• Gases flow and can change shape.
• Gases have a variable volume that can change.
• Gases can be compressed.
