Answer:
A) Tissue
Explanation:
Cells are the basic and fundamental units of all living organisms. Plants, like every other multicellular living organisms, are composed of cells that perform different functions. A group of cells that perform similar functions make up or form TISSUES, tissues that work together form the ORGAN, organs that work together to perform same function form the ORGAN SYSTEM.
In plants, sieve tubes and companion cells work together to carry out a similar task in plants, which is to transport nutrients and sugar inside the plant. Since sieve tubes and companion cells work together to fulfil same task, they collectively form a tissue in plants called PHLOEM tissue.
Answer:
c. They usually have certain special functions.
Explanation:
Multicellular organisms have more than one cell in their body. They exhibit division of labor. This means that various cells of multicellular organisms are differentiated to perform specific functions. Therefore, there are different types of cells in the bodies of multicellular organisms that differ from each other with respect to structure and functions. For example, the cells of root hairs in plants perform the function of absorption of water from the soil while the mesophyll cells of their leaves perform the function of photosynthesis.
Answer:
Sedimentary rocks
By studying sedimentary rocks from the Earth's crust, we can learn about the history of how Earth's surface has changed over time
