Which group of plants lacks true roots, stems, and leaves?

A seedless vascular plants
B nonvascular plants
C nonflowering seed plants
D flowering plants
This quetion is from edgenutiy

Answers

The nonvascular plants are the group of plants that lacks true roots, stems, and leaves. The correct option is B.

What are non-vascular plants?

Plants lacking a circulatory system made up of xylem and phloem are referred to as non-vascular plants.

They may instead have more basic tissues with tailored capabilities for the internal transfer of water.

Mosses, hornworts, and liverworts are examples of nonvascular plants. They don't have leaves, stems, or roots.

Nonvascular plants require a damp environment, are low-growing, and reproduce using spores.

The primary distinction between vascular and nonvascular plants is that the former have a vascular system for the transportation of food and water, whilst the latter lack circulatory tissues.

The majority of liverworts are quite rare in the park and need to be close to water to survive. Mosses and liverworts are tiny, non-vascular, primitive plants.

Thus, the correct option is B.

Greek philosophers such as Democritus and Aristotle had ideas about the composition of matter. For example, Democritus believed matter was made of tiny, solid spheres that he called atomos, and Aristotle thought matter was made of earth, water, fire, and air. Aristotle's idea of matter was the accepted idea for over 2,000 years until John Dalton came up with a new theory about matter based on his experimental data. Which of the following best explains why Dalton’s theory became more widely-accepted over Aristotle's theory?


Aristotle’s theory did not have enough direct evidence due to poor observational tools.


Dalton’s theory had repeated observations which were supported by extensive evidence.


Dalton’s theory was more complete because more respected scientists found the ideas possible.


Aristotle’s theory became the law of conservation of mass when he documented phase changes of matter.

It is generally acknowledged that as human beings age, it becomes more difficult for them to lose weight, or even maintain their current weight. People find they have to eat less and/or exercise more to maintain a healthy weight.

Which is the most likely explanation of why weight loss/maintenance becomes more difficult as people age?

a). As humans age, they becomes less active and use their muscles less; therefore, less chemical energy is converted to thermal energy.
b). As humans age, the process of extracting energy from the food becomes less efficient, so more food is needed to provide the same amount of energy.
c). As humans age, they become injured more often and need to increase the amount of food they eat to make repairs to body tissue.
d). As humans age, the body does not convert chemical to thermal energy, so they do no burn off any calories when exercising.
