Plants first appeared on land nearly 500 million years ago. Since these first colonizers, there have been three key developments that allowed plants to diversify & colonize an immense range of habitats. Put these three key developments from the following in in the order in which they evolved, oldest to newest:

a. Cellular respiration
b. Seeds
c. Vascular tissue
d. flowers cels
e. Photosynthesis
f. Specialized Cell

C. Vascular tissue, B. Seeds and then D. flowers

Explanation:

The land plants were evolved from the aquatic plants especially algae named Chara.

The land plants adapted to survive on the terrestrial habitat by forming structures first of which is the vascular tissues.

The vascular issues developed in the trees in the group of organisms called the pteridophytes. Later plants started protecting their embryos in a hard coat layer which could protect the embryos during adverse conditions. These structures were later called the seeds which were a characteristic feature of the gymnosperms. Later plants developed the flowers which acted as modified reproductive structures and the plants were called angiosperms.

Thus, C. Vascular tissue, B. Seeds and then D. flowers is correct.

im gonna compare the cells to jobs in factory. give brainliest

job in the factory //       cell organelle   //  

shipping/receiving

department                 plasma membrane    

chief executive officer// nucleus

factory floor // cytoplasm

assembly line// endoplasmic reticulum

workers in the assembly line //ribosomes

finishing/packaging department //golgi apparatus

maintenance crew //lysosomes

support beams (walls, ceilings, floors) //cytoskeleton

power plant //mitochondria/chloroplasts

here's what each part of the cell does:

plasma membrane :

regulates what enters and leaves the cell; where cell makes contact with the external environment

nucleus :

controls all cell activity; determines what proteins will be made

cytoplasm :

contains the organelles; site of most cell activity

endoplasmic reticulum:

where ribosomes do their work

ribosomes :

build the proteins

golgi apparatus :

prepares proteins for use or export

lysosomes :

responsible for breaking down and absorbing materials taken in by the cell

cytoskeleton :

maintains cell shape

mitochondria/chloroplasts :

transforms one form of energy into another

bacteria could be both, harmful and to us. harmful bacteria could make us sick and probably even by getting the chances of getting a disease, but good bacteria fight it off with your immune system. there is always bacteria everywhere we go. we need to make sure to wash our hands after using the restroom, before eating, after eating, after petting an animal too. so you see, bacteria is everywhere and is harmful or . i hope this . : ) : ) : )
