i need to answer these statements true or false:- ive answered some but stuck on others.
1)only animals respire - false
2)respiration uses oxygen
3)respiration uses up carbon dioxide
4)only green plants photosynthesise-true
5)all living things respire- true
6)plants use up and produce oxygen- false
7)plants use up and produce carbon dioxide- false
8)plants photosynthesise 24 hours a day- false
9)photosynthesis produces oxygen
10)plants only respire at night- false
thankyou!
1 False

8 False
9 False
10 True
1) Only animals respire - False
To answer this question, you can use your basic knowledge about the process of respiration. Respiration is the process of exchanging gases, usually oxygen and carbon dioxide, between an organism and its environment. While animals primarily respire through lungs, many other organisms also respire through different mechanisms. Plants, for example, have tiny openings called stomata on their leaves through which they can exchange gases.
2) Respiration uses oxygen - True
To answer this question, you can recall that respiration involves the breakdown of glucose molecules to release energy. This process requires oxygen in animals, as they have specialized respiratory systems (such as lungs) to take in oxygen for respiration.
3) Respiration uses up carbon dioxide - False
To answer this question, you can recognize that during the process of respiration, oxygen is consumed and carbon dioxide is produced as a waste product. So, respiration does not use up carbon dioxide but actually produces it.
4) Only green plants photosynthesize - True
To answer this question, you can recall that photosynthesis is the process by which plants convert light energy into chemical energy in the form of glucose. This process occurs in the chloroplasts of plant cells, which contain a pigment called chlorophyll, giving plants their green color. So, only green plants are capable of photosynthesis.
5) All living things respire - True
To answer this question, you can recall that respiration is a fundamental process for all living organisms. It is necessary for the production of energy required for various life processes. While the mechanism of respiration may differ in different organisms, all living things respire in some way or another.
6) Plants use up and produce oxygen - False
To answer this question, you can recall that during photosynthesis, plants produce oxygen as a byproduct. However, during respiration, plants consume oxygen and produce carbon dioxide, just like animals.
7) Plants use up and produce carbon dioxide - False
To answer this question, you can recognize that plants do not use up carbon dioxide but actually consume it during the process of photosynthesis. They convert carbon dioxide into glucose, releasing oxygen as a byproduct.
8) Plants photosynthesize 24 hours a day - False
To answer this question, you can consider that photosynthesis requires sunlight as an energy source. Therefore, plants can only photosynthesize when there is enough light available. This means that plants cannot photosynthesize at night, resulting in it being false that they photosynthesize 24 hours a day.
9) Photosynthesis produces oxygen - True
To answer this question, you can recall that one of the products of photosynthesis is oxygen. Through the process of photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose and release oxygen as a byproduct.
10) Plants only respire at night - False
To answer this question, you can recall that plants respire continuously, just like animals. Respiration is vital for the production of energy necessary for plant growth and metabolism. Therefore, it is false that plants only respire at night.
