Test: Cell: Structure and Functions - Question 1

What is the fundamental unit of life, responsible for all life processes?

Detailed Solution: Question 1

Cells are considered the fundamental unit of life. They are responsible for carrying out all life processes in living organisms. The cell theory, proposed by scientists like Schwann, Schleiden, and Virchow, emphasizes the significance of cells in the structure and functions of living entities.

Test: Cell: Structure and Functions - Question 2

In prokaryotic cells, where is the genetic material located?

Detailed Solution: Question 2

Prokaryotic cells lack a distinct nucleus, and their genetic material is freely suspended in a region called the nucleoid.

Test: Cell: Structure and Functions - Question 3

Which cell organelle is responsible for energy transactions vital for cell survival?

Detailed Solution: Question 3

Mitochondria, are double membrane-bound organelles responsible for energy transactions crucial for the survival of the cell. They play a central role in cellular respiration.

Test: Cell: Structure and Functions - Question 4

Who was the first biologist to discover cells?

Detailed Solution: Question 4

Robert Hooke is credited as the first biologist to discover cells. In 1665, he observed a piece of bottle cork under a compound microscope and coined the term "cells" to describe the small structures he observed. This discovery laid the foundation for the study of cells in Cell Biology.

Test: Cell: Structure and Functions - Question 5

What distinguishes eukaryotic cells from prokaryotic cells?

Detailed Solution: Question 5

Eukaryotic cells are characterized by the presence of a true nucleus, a feature that distinguishes them from prokaryotic cells. The nucleus in eukaryotic cells houses the genetic material.

Test: Cell: Structure and Functions - Question 6

What is the main function of the cell membrane?

Detailed Solution: Question 6

The cell membrane controls the movement of substances in and out of the cell. It acts as a selective barrier, regulating the passage of various molecules and maintaining the integrity of the cell.

Test: Cell: Structure and Functions - Question 7

What is the function of lysosomes in a cell?

Detailed Solution: Question 7

Lysosomes play a pivotal role in the cell by digesting unwanted materials, contributing to the cell's cleanliness and recycling processes.

Test: Cell: Structure and Functions - Question 8

What is the primary function of the nucleus in a cell?

Detailed Solution: Question 8

The nucleus of a cell contains the hereditary material (DNA) and controls genetic information. It sends signals for the cell to grow, mature, divide, and undergo programmed cell death.

Test: Cell: Structure and Functions - Question 9

What does the modern version of the cell theory state about cells?

Detailed Solution: Question 9

The modern version of the cell theory includes the postulate that genetic information is passed on from one cell to another. This emphasizes the continuity and transmission of genetic material between cells.

Test: Cell: Structure and Functions - Question 10

Which organelle is exclusive to plant cells and acts as a structural support?

Detailed Solution: Question 10

Chloroplast, unique to plant cells, contains chlorophyll and is involved in photosynthesis. It contributes to the structural support of plant cells.
