Cell wall is surrounded by the cell membrane which provides structure and supports the cell. Cell membrane is an enclosed organelle that separates interior and located around the outside of the cell wall. The vacuole store water and contain substances including ions, nutrients, and waste. Nucleus is the boss and houses cell DNA. The nucelous is involved in the synthesis of ribosome RNA. The nuclear membrane is a double layer between the nucleus and cytoplasm. Organelle that has light energy and carbohydrates from carbon dioxide and water is the chloroplast. Extensive system of external membrane that moves protein and other substances through the cell is the endoplasmic reticulum. An organelle that harvest energy to make energy and ATP is the mitochondria. Tiny bodies in a cell that involve in protein are called ribosome. The jelly- like substance in the interior and hold the cells together is the cytoplasm. The golgi body or also known as the golgi apparatusCells are the structural and functional units of all living organisms. Cells may have different qualities according to the organisms that they form and according to tissue types of the species. There are some similarities and differences between plant cell and animal cell in terms of their shapes, the organelles that they have, the features of the organelles that are present in both of them. Animal cells do not have chloroplasts plastids, and cell wall. Animal cells have cytoplasm, endoplasmic reticulum, ribosomes, mitochondria, centrosome, golgi apparatus, cell membrane, microtubules, lysosomes, nucleus and nucleolus. Animal cells also have vacuoles, but vacuoles in animal cell are small in size. Animal cells…
There are two classes of cells that exist in biology today, there are prokaryotic cells and there are eukaryotic cells. A prokaryotic cell is a cell that has no nucleus which consists of bacteria; a eukaryotic cell is a cell that has a nucleus. There are two types of eukaryotic cells in biology; plant and animal cells. Plant cells have organelles in each cell that helps then function and go through processes such as photosynthesis. Each cell in our body consists of organelles that help…
Both plant and animal cells are eukaryotic cells which mean they have a ‘true’ nucleus. Animal cells can come in an array of sizes and unusual shapes, unlike a plant cell which is typically rectangular or cube shaped.
What can be found in a Plant Cell and an Animal Cell?
Cell Membrane - This surrounds the cytoplasm in the cell, enclosing its contents. It is thin and semi permeable and allows substances to move through it.
Cytoplasm - a gel like substance…
Everywhere around each organelle inside the cell membrane. Protects and provides support to each organelle. It keeps the organelles supported so it is quite important.
Nucleus Quite large Circular Plant/Animal
Usually surrounded by ER Contains materials such as DNA and controls cell activities Very important because it controls the cell
Nucleolus Average Circular Plant/Animal
Inside the Nucleus Produces Ribosomes Not so important
Ribosomes Very small Little dots Plant/Animal…
dependant on life plants?
Plants are very essential for survival to all forms of life, by providing us with oxygen and being a major supplier of food. Plants practice photosynthesis and the product of it bring us oxygen, also help removing the excess of carbon dioxide out into the earth’s atmosphere and purifying and distributing the water of the planet, by a method called “transpiration”.
Human nutrition is dependent on plants, either indirectly or directly. Throughout years, many plants have been used…

The Role of Cultivated Plants in the Living World
After reading the chapter you should be able to:
Understand the role of cultivated plants as food sources.
Understand the benefits of cultivated plants in addition…
means of two ways: food or animals. In the course of time, our civilization has expanded from the domestication of mammals. However, humans discovered that land creatures to be more desirable than marine animals. Reason is that, sea creatures were tricky to breed and preserve during the early pre historic years. So, humans relied mostly on animals for nutrition, clothing, tools, and transportation. To this day humans depend on livestock to meet their day-to-day needs. Animals have brought countless benefits…

Difficulties of life on land
* Plants need a constant supply of water to deliver materials to and transport wastes away from the cells
* Plants need light for photosynthesis but too much light will dry plant tissues exposed to air due to the increased evaporation of water
* Gas exchange- In water, CO2 is dissolved in it and plants can obtain it by diffusion. Land plants need a different mechanism
* Reproduction- Aquatic organisms produce swimming…
Around the world the talk of cloning animals has increased significantly. Because of the need for food or human selfishness ,many animals have become extinct. Whoever acquires a disease or virus usually gets the virus from another person or from the original host usually a animal. Because the main cause of many disease is still embedded in the corpse of the extinct animal, we need to bring back extinct animals. If we bring back animals we would enable the power to make special proteins which are…

Changes in the distribution of plants and animals in response to climate change
Changes in the distribution of plants and animals in response to climate change is something we live with every single day and not many people know the massive effects it has on our plants and animals. Climate change is not a hoax, it is real and very serious and if we do not do something about it now then it will ruin our planet and destroy our future. Climate…
