The circulatory system is responsible for the transportation and delivery of materials in living organisms.
The circulatory system, also known as the cardiovascular system, is a complex network of blood vessels, the heart, and blood. Its primary function is to transport oxygen, nutrients, hormones, and waste products throughout the body. The heart pumps blood, while arteries carry oxygenated blood away from it, and veins return deoxygenated blood to it. This system sustains life by ensuring the delivery of essential substances to cells and tissues.
The structure responsible for the transportation and delivery of materials in living organisms is the circulatory system. In humans, the circulatory system consists of the heart, blood vessels, and blood. The heart pumps oxygenated blood to the body's organs and tissues through the arteries, and deoxygenated blood is returned to the heart through the veins.

A Chloroplasts contain DNA.
B According to the endosymbiosis theory, they were formed by an ancestral eukaryote
consuming photosynthetic bacteria.
C Thylakoids are pigments found within chloroplasts that give plants their green color.
D Photosynthesis occurs in the chloroplast
The statement regarding chloroplasts is false - C Thylakoids are pigments found within chloroplasts that give plants their green color.
In the plant cells and other autotrophic cells, there is a cell organelle called chloroplast that is essential for every ecosystem as it produces food for their energy.
Chloroplasts:
Thus, the statement regarding chloroplasts is false - C.
Learn more about:
B. They capture nitrogen from the atmosphere and convert it into forms that plants can use, like ammonia.
C. They convert sunlight into chemical energy which is then stored in the nitrogen.
D. They convert ammonia from animal feces and urine into forms that plants can use.
