BIOLOGY

9 September 2020 Makassar, Makassar City, South Sulawesi, Indonesia

Hi kids, congratulations you made it to the end of biology chapter  in this semester.  As you notice that this chapter focuses on living things, how they adapt, how they eat, how they reproduce and even how they connect each other (between plants, animals and human beings). Plenty of topics have been explained to you in biology chapter started from life processes until how human can stay healthy. So, in this article I am going to highlight what have you learnt about biology.


Begins with life processes, a process that keeps living things (animals, plants and human beings) alive, that include nutrition, movement, growth, reproduction, respiration, sensitivity and excretion. As living things grow, their sensitivity makes them aware of their surroundings because of their senses. There are five senses attached on them - sight, hearing, smell, taste and touch which are all detected through different sense organs such as eyes, ears, nose, tongue and skin. 


Living things can be sorted based on their distinctive features, helping them adapt well in their habitat (a place where plants and animals live). The organisms that live in a habitat are adapted to live in the habitat. Owing to this fact, scientists can easily classify them by looking at how they are similar to and different from each other. The sorting of living things into groups is called classification.

Plants, on the other hand, have four main parts such as roots, stem, leaves and flowers. It starts its life cycle from germination when conditions are right which means the seed can only germinate when it gets enough water, warmth and air. Once it becomes seedlings, a sufficient amount of water, light, warmth and air, is required for them to grow healthy. A fully-grown plant will produce flowers that contain the reproductive organs of the plant (both female and male) which make and receive pollen.


The male parts, known as stamen, consist of the anther, which produces pollen, and filament, which is a stalk that supports the anther. Meanwhile, female parts (known as pistil or carpel) consist of stigma, style and ovary, which contains ovule. 


The transferring of pollen from the anther to the stigma is called pollination (can either be done by wind or insects). Each pollen grain then grows a tube down to the ovule in a process known as fertilisation, resulting in the ovary becomes a fruit and the ovule becomes seed (seed production). Finally, the grown-fruit disperse its seeds by animals, water, wind or explosion (seed dispersal) - and the cycle starts again.

However, in what ways the plants help the animals?🤔

Well, it's simple, the animals cannot make their food so must obtain it from plants or other animals - this is what we called a food chain. So, the plants provide food for the animals and when animals die, they will become decomposer which provides minerals for the plants. wow, amazing right?

Nevertheless, this chain does not go as it supposed to be due to the careless of human activities such as cutting down trees to build up power station that causes organisms lost their habitats and pollute the atmosphere with greenhouse gases, even worst resulting some species go extinct. For these reasons, the human must apply 3R’s (recycle, reuse and reduce) to keep the life balance on Earth. 

Turning to humans, complicated and complex walking creatures on Earth, depend on both plants and animals for their survival. They require a balanced diet that covers the nutrient groups (proteins, fats, carbohydrates, vitamins, minerals, fibre and water) to stay fit. 


Human’s body is divided into the head, the torso (with the upper part being the thorax and the lower part being the abdomen) and the limbs, which are attached to the torso. Humans have a skeleton of bones inside their body. Those bones grow as the body grows. They support and protect parts of the body and help us move. This skeleton works along with the muscles, that work in pair - one contracts and another relaxes such as biceps and triceps in the arm and quads and hamstring in the leg. The power of the movement comes from the muscles that attached to the bones when energy is adequately fulfilled through the foods that we consume. 


Taking regular exercise is vital for them to avoid fat building up the body, which can damage the heart. Exercise also makes the heart and muscles stronger and helps the joints between the bones move more easily.

 

So that’s the highlight of biology chapter. Shortly, all living things (plants, animals and humans) are connected to each other to continue supporting their life. I hope that it can help you understand it. 

Now, let's try this!

Write your opinion about biology chapter in one or two sentences. It could be about your favourite topics, how far you could understand about it or perhaps the topics that you need more explanation about. Explain your answer in the comment box below!

  1. I like the Nutrient topic,cause i just love to study about food and types of food and i already know that if some types of food if we consume to much,that can damage our body.

  5. The biology chapter is interesting because it talks about all living things. Biology explains about how living things do life processes.

  6. It's actually pretty hard to be honest, especially the food pyramid, for me
