Summary: Cells are the building blocks for every living thing. It means all humans, animals, and plants consist of cells. Robert Hooke discovered the cells in 1665. Based on the structure of the cell, researchers or biologists divide living things into two, bacteria (prokaryotes) and all types of animals and plants (eucaryotes). Learning about the cells of plant and animal help the students to have the base foundation of biology knowledge for their future studies.
What is the Definition of a Cell?
A cell might be a familiar term for many people. However, what is the actual definition of it? According to Medline Plus from the National Library of Medicine, cells are the building blocks for every living thing. It means all humans, animals, and plants consist of cells. For a fact, there are trillions of them inside one living form. They have a purpose in building the body's structure, changing nutrients from foods into energy, and other functions. Cells also can make copies of themselves since they carry a body of hereditary material. It arrives from the Latin word "cella", which means a "store-room" or "chamber". The name made sense since a cell is a compartment for numerous elements that control the living thing. Most of the time, a single cell is a complete and functional organism by itself. Based on the structure of the cell, researchers or biologists divide living things into two, bacteria (prokaryotes) and all types of animals and plants (eucaryotes).
How to Explain Animal Cell to Seventh-Grade Students?
Biology is one of the subjects that middle-school students should take. Cell learning is one of the topics that the students should master. Hence, teachers should plan a lesson activity that excites yet helps the stents to grasp the lesson. Starting with the animal cells, it is a foundation blocks that build animals. It consists of abundant elements that help the animal function well. Animal cells are eukaryotic, meaning they do not have cell walls. However, they carry a membrane-bound nucleus along with additional organelles. Organelle is a tiny structure in the cell with a membrane and a particular function. The dimensions of animal cells are around a few microns to some millimetres.
Animal cells are multicellular, conveying many cells work collectively to build a complete and functional living organism. The animal has some popular cells such as stem, intestinal, red blood, muscle, liver, and nerve cells. Even though animal cells lack cell walls, they have solid structures to protect the tissue and organs inside their body called skeleton and cartilage. There are some types of animal cell shapes, flat, cylinder, spherical, concave, rectangular and more. One of the unique characteristics of animal cells is their irregular shapes, as they do not have a cell wall.
What is a Plant Cell Learning for Seventh-Grade Students?
Besides learning about animal cells, seventh-grade students have to study plant cells. A cell wall surrounds the plant cells, which shape the plant structure. Similar to animal cells, plant cells are eukaryotic ones. Plant cells have the shape of rectangular and have larger forms than animal cells. Even though both animal and plant cells are eukaryotic, they have some different cell functions. One of the crucial organelles in cell plants is the chloroplast. It is a place where the photosynthesis process occurs. Photosynthesis is a process where plants use sunlight to convert carbon dioxide and water into their meals. This process depends on the green pigment of the plants, known as chlorophyll. Photosynthesis let out oxygen as the byproduct, which help human breathe. Hence the heavy role of plants in human life, teachers should ask the students to take care of the nature around them.
Why is Learning Animal and Plant Cells Important?
Plants and animals are living things that are close to human nature. We can encounter them many times in a day. Hence, the students should learn about plants and animals, even their cells. Having an interest in taking care of plants and animals is a way for humans to respect and be thankful for what nature has provided to us. Plants and animals provide various nutritious meals, providing oxygen to help us breathe, produce many essences for our medicines and more. It will teach the students that our actions towards nature will affect human life. Learning about the cells of plant and animal help the students to have the base foundation of biology knowledge for their future studies. It will be beneficial for the students to open more doors for their work and career opportunities.
Who is the Scientist that Discovered Cells?
Based on National Geographic, Robert Hooke discovered the cells in 1665. This discovery has had a significant impact on the biology world. It gives other scientists at those times an understanding of the building blocks inside every living form. The discovery of the cell has led to refinements in biological technology and treatment. This finding led to scientists who work on personalized medicine, which allows us to produce stem cells from our very own cells and then use them to comprehend disease procedures.
