I believe that this is true
<u>Meristematic Cells</u>
Contains meristimatic cells, apical meristems are found in the tips of the roots and in the buds of the shoots. They supply cells for the plants to grow in length.
Apical Meristems are found in herbaceous plants, woody plants, grasses, and flowering plants.
<span>In flowering plants, shoot apical meristem develops into an inflorescence meristem which produces the floral meristem. The floral meristem is responsible for the production of the sepals, petals, stamens, and carpels of the flower.</span>
The answer is <span>C) in warm, shallow seas.
</span>
About 500 million years ago, many multicellular organisms lived in
the seas. It was a rich life in shallow, warm, and continental
seas. The climate was favorable. Reef-forming corals, as well as the first true
vertebrates, some fish, appeared. Trilobites were diverse and
rich. The name trilobite means three lobes in which their body is divided. They lived in warm shallow seas. They avoided a great extinction of species in that time before they were <span>covered by sediment.</span>
I believe the answer is B
