Which best explains why angiosperms are the most diverse and successful plant group today?

Which best explains why angiosperms are the most diverse and successful plant group today? Reproduction is aided by flowers, protected seeds, and insect pollinators. Xylem transports water and nutrients in the plant, and phloem transports water and sugar. You just studied 15 terms!

What is a key adaptation that enables plants to survive on land?

Plant adaptations to life on land include the development of many structures — a water-repellent cuticle, stomata to regulate water evaporation, specialized cells to provide rigid support against gravity, specialized structures to collect sunlight, alternation of haploid and diploid generations, sexual organs, a …

Why the angiosperms are such a successful and diverse group of plants?

With more than 250,000 species, the angiosperm phylum (Anthophyta) is second only to insects in terms of diversification. The success of angiosperms is due to two novel reproductive structures: flowers and fruit. The function of the fruit is seed dispersal. They also protect the developing seed.

Why are angiosperms the most successful plant group?

Angiosperms have been so successful because of their compact DNA and cells. Angiosperms – you are one magnificent bunch of plants.

What is structure helps them respond to and survive in their environment?

An adaptation is an inherited characteristic that helps an organism survive and reproduce in its environment.

How did plants move to land?

Plants evolved from living in water to habiting land because of genes they took up from bacteria, according to a new study which establishes how the first step of large organisms colonising the land took place.

How do the roots help the plant grow?

But roots play a critical role in the life of a plant. They anchor the plant to support the shoots above. They absorb water and mineral nutrients and conduct them upward. They store carbohydrates and other nutrients that are a source of energy for woodies, perennials, and biennials as they awaken and grow in spring.

What gives support to the plant?

Answer: Stems hold the plant upright and support it. They also transport water, minerals and sugars to the leaves and roots.

What is the general idea of hypothesis testing?

The general idea of hypothesis testing involves: Making an initial assumption. Collecting evidence (data). Based on the available evidence (data), deciding whether to reject or not reject the initial assumption. Every hypothesis test — regardless of the population parameter involved — requires the above three steps.

How do you make an initial assumption in statistics?

In the practice of statistics, we make our initial assumption when we state our two competing hypotheses — the null hypothesis ( H0) and the alternative hypothesis ( HA ). Here, our hypotheses are: In statistics, we always assume the null hypothesis is true. That is, the null hypothesis is always our initial assumption.

Why were angiosperms so successful in reducing genome size?

They found that angiosperms were the only group of plants that went through a genome downsize during this period. This is what made them so successful. An evolutionary tree that shows how genome size compares between different groups of land plants. Click for more detail.

How do you find the critical value of a hypothesis?

Step 1 State the hypotheses and identify the claim. Step 2 Find the critical value(s) from the appropriate table. Step 3 Compute the test value. Step 4 Make the decision to reject or not reject the null hypothesis.
