What are main characteristics of seedless vascular plants?
Ferns, club mosses, and horsetails share two characteristics. They have true vascular tissue and they do not produce seeds. Instead of seeds, these plants reproduce by releasing spores.
What are the three main groups of vascular plants?
The 3 main groups of seedless vascular plants are: ferns, horsetails and club mosses.
Why do animals need plants?
the main, maybe most significant reason for plants needing animals is for fertilization. Plants have evolved to reproduce effectively. Seeds need to be dispursed- note how many seeds are designed to attach to the fur of animals such as foxes/ cats or dogs and pollination, vital for genetic variation- sexual reproduction is carried out by bees. Some plants rely on birds eating the seeds as the seeds are only able to grow when they have been excreted with sufficient nutrients from the birds faeces.
Do bald eagles reproduce sexually or asexually or both?
All vertebrates reproduce sexually. Birds are one of the main groups of vertebrates, so they reproduce sexually.
What are the 2 main groups of living things?
The two main groups of living things are- a) Plants b) Animals
Scientists today divide plants into two large groupsd basedv on?
scientists today divide plants into two large groups based onwhat are the two large groups of plants Edited answer: Based on vasculature, the plant kingdom is divided into- 1. Vascular and 2. Non-vascular plants.
Four characteristics common to all seed plants?
Some characteristics of seed plants are that they produce seeds to protect and nourish sporophytes, and the sperm of seed plants do not need water to get to the egg. Pollen can be transported by wind, human, or animals. Another characteristic is the gametophytes are small and form within the reproductive structure of the sporophytes.
What is the main difference between agiosperms and gymnosperms?
In angiosperm seeds are enclosed inside the ovary whereas in gymnosperm seeds are naked (i. e. born on megasporophyll) Gymnosperms have archegonium for egg whereas in angiosperms it is replaced by an embryo sac.
How do you get a mooshling?
You have to plant certain combination of plants. and you can get the seeds in main street and the shop is called moshling seeds
What are the 2 main groups of plants?
the answer is they are divided into 2 groups-vascular and non-vascular
What is the main function of seeds?
The seeds are used by plants to overcome the adverse climatic conditions. Seeds are also a means of propagation in plants. The dispersal of plant population is also achieved through seeds.
Do seeds and spores have both multicellular and embryos?
While they have the same function- to reproduce- the main difference between seeds and spores is that seeds come from flowering plants (they are the ripened ovules of the plants) and spores are produced by non-flowering plants (they are tiny reproductive bodies). Seeds, since they are ripened ovules, have plant embryos with a food store and a protective covering around all of that. On the other hand, spores do not have stored food resources and can be made of one or many cells. So, seeds are multicellular while spores are usually unicellular, and seeds contain embryonic plants while spores do not (they themselves are the tiny reproductive bodies).
