Hallo all stemians friends, On this occasion I will share new knowledge about how to facilitate learners to understand the wave easily is by creating a simple media about cell models.
Learning objectives for students after observing animal and plant cell models, learners can describe parts of cells and their organelles.
Simple media that can be used :
Animal and plant cell models
Theory
The cell (from Latin cella, meaning "small room") is the basic structural, functional, and biological unit of all known living organisms. A cell is the smallest unit of life that can replicate independently, and cells are often called the "building blocks of life". The study of cells is called cell biology. Source
The animal cells are smaller, non-fixed, have lysosomes and centrosomes, have no cell walls, plastids (chloroplasts) and vacuoles. While plant cells are larger, they are fixed, have plastids (chloroplasts), cell walls and vacuoles, do not have lysosomes and centrosomes.
Differences of Animal Cells and Plant Cells
There are some differences between animal cells and plant cells:
Animal Cells
- The size of an animal cell is smaller than that of a plant cell
- Does not have a plastid (chloroplasts)
- It has no cell walls
- Has a lysosome
- Has a centrosome
- Has a non permanent form
- It does not have a vacuole (although there is also a vacuole but its size is small)
Plant Cells
- Plant cell size is larger than animal cells
- Generally have plastids (chloroplasts)
- It has cell walls and cell membranes
- Do not have lysosomes
- Do not have centrosomes
- Have a fixed form
- It has a large size vacuole and usually amounts to a lot...
Preparation and use of media
Animal and Plant Cell Models:
This medium can be used to concrete the actual cell shape in three dimensional form.
Creation
- Materials and tools
a) Material:
• Clay (amount will be determined after trial)
• Water paint at least 6 colors
a) Tools:
• Small knife 1 piece
• 6 brushes
How to make this models
a) Form clay into a model of animal and plant cells as shown above.
The basic shape of the cell model
b) Raft the cell model complete with organelles like the one in the picture.
How to assemble the cell organelle
c) Dry up the cell model until dry.
Cell model that has been dried
d) Give different colors to each different organelle.
The cell model being painted
How to Use this miniature models to the students
- The teacher distributes the cell model to the student group.
- Ask students to observe the parts of the cell and its organelles.
- Ask students to write the names and functions of the animal and plant cell parts and their organelles on the paper provided.
