Step-by-step solution for: Plant and Animal Cell Worksheets
I will solve this "Cell Facts" worksheet by filling in the blanks with the correct biological terms. I'll go through each question one by one, providing the answer and a brief explanation for each.
---
1. _Cell_ is the basic structural, functional and biological unit of life.
*Explanation:* The cell is universally recognized as the fundamental unit of life. All living organisms are composed of one or more cells, which carry out all the processes necessary for life.
---
2. Cell was discovered by _Robert Hooke_.
*Explanation:* In 1665, Robert Hooke used an early microscope to examine a thin slice of cork and observed small, box-like structures, which he called "cells" because they reminded him of the small rooms (or "cellulae") in a monastery.
---
3. Organisms can be classified as _unicellular_ and _multicellular_.
*Explanation:* Organisms are broadly categorized based on the number of cells they contain. Unicellular organisms, like bacteria and amoebas, consist of a single cell. Multicellular organisms, like plants and animals, are made up of many specialized cells working together.
---
4. _Cytology_ is the study of cell structure and function.
*Explanation:* Cytology is the branch of biology that focuses on the structure, function, and chemistry of cells. It is sometimes used interchangeably with cell biology.
---
5. Single-celled organisms are called _unicellular organisms_.
*Explanation:* This is a direct definition. Any organism that consists of only one cell is termed unicellular.
---
6. Chloroplast and chromoplast are types of _plastids_.
*Explanation:* Plastids are a group of membrane-bound organelles found in plant cells and some other eukaryotic organisms. Chloroplasts are responsible for photosynthesis, while chromoplasts synthesize and store pigments.
---
7. _Prokaryotes_ and _eukaryotes_ are the two main types of cells.
*Explanation:* Cells are divided into two major categories based on their internal organization. Prokaryotes (like bacteria) lack a nucleus and other membrane-bound organelles. Eukaryotes (like plant and animal cells) have a nucleus and complex organelles.
---
8. Cell membrane is also known as the _plasma membrane_.
*Explanation:* The cell membrane, or plasma membrane, is a selectively permeable barrier that surrounds the cell, controlling the movement of substances in and out.
---
9. _Organelles_ includes the cytoplasm and the nucleus.
*Explanation:* While the statement is slightly misleading (the cytoplasm and nucleus are parts of the cell, not included *in* organelles), the intended answer is likely "organelles." Organelles are specialized structures within a cell that perform specific functions. The nucleus is an organelle, and the cytoplasm is the gel-like substance that fills the cell and contains the organelles.
---
10. _Muscle_ and _bone_ are like the skeleton and muscles of the cell.
*Explanation:* This is a metaphorical comparison. The cytoskeleton provides structural support and shape to the cell, similar to the skeleton in an organism. Motor proteins and actin filaments allow for movement within the cell, analogous to muscles.
---
11. Cells contain a number of functional structures called _organelles_.
*Explanation:* Organelles are the "little organs" of the cell, each with a specific role, such as mitochondria for energy production or ribosomes for protein synthesis.
---
12. Rough ER and smooth ER are the two types of _endoplasmic reticulum_.
*Explanation:* The endoplasmic reticulum (ER) is a network of membranous tubules and sacs. The rough ER has ribosomes attached and is involved in protein synthesis, while the smooth ER lacks ribosomes and is involved in lipid synthesis and detoxification.
---
13. We cannot see most cells without the aid of a _microscope_.
*Explanation:* Most cells are microscopic, meaning they are too small to be seen with the naked eye. A microscope is required to magnify them to a visible size.
---
14. _Chloroplasts_ are also known as the solar panels.
*Explanation:* Chloroplasts capture sunlight and convert it into chemical energy through photosynthesis, much like solar panels convert sunlight into electricity.
---
15. Cells group together to form _tissues_, and tissues group together to form _organs_.
*Explanation:* This describes the hierarchical organization of multicellular organisms. Similar cells form tissues (e.g., muscle tissue), and different tissues combine to form organs (e.g., the heart).
