what is the difference between gymnosperms and angiosperms quizlet?
147615
Gymnosperms have naked seeds, don't have flowers or fruits, and have a haploid endosperm in the seeds (endosperm is produced before fertilization), while Angiosperms have enclosed seeds, flowers, fruits, and have a triploid endosperm in the seed (endosperm produced during triple fusion).

What is the one most obvious difference between the gymnosperms and angiosperms? The gymnosperms don't form flowers while the angiosperms do. The photosynthetic pigments in angiosperms are likely to be most closely related to those in: green algae.

Compared to humans, plants have a single large vacuole, which is centrally located. ... This is the most significant difference among plants and humans because humans do not contain chloroplasts. Plants are capable of making their own food, while humans depend on other living things for survival.

Flowering plants mature more quickly than gymnosperms, and produce greater numbers of seeds. The woody tissues of angiosperms are also more complex and specialized. Their seeds are enclosed in a fruit for easy dispersal by wind, water, or animals.

The main difference between plant and animal vacuoles is that plant vacuoles are large in size and are single in number whereas animal vacuoles are small in size and are more in number. Vacuoles are more important in plant cells to maintain the turgor pressure.

['All angiosperms have flowers at some stage in their life. ... ', 'Angiosperms have small pollen grains that spread genetic information from flower to flower. ... ', 'All angiosperms have stamens. ... ', 'Angiosperms have much smaller female reproductive parts than non-flowering plants, allowing them to produce seeds more quickly.']

--Angiosperms are a taxonomic class of plants in which the mature seed is surrounded by the ovule (think of an apple). ... Angiosperms are trees have broad leaves that usually change color and die every autumn. Oaks, maples and dogwoods are examples of deciduous trees.

These seed plants fall into two groups, angiosperms and gymnosperms. Angiosperms are the flowering plants. Their seeds develop inside a female reproductive part of the flower, called the ovary, which usually ripens into a protective FRUIT. Gymnosperms (conifers, Ginkgo, and cycads) do not have flowers or ovaries.

['Discuss how angiosperms and gymnosperms reproduce. ... ', 'In angiosperms, the pistil is the female reproductive structure found in flowers, and consists of the stigma, style, and ovary. ... ', 'In gymnosperms the cone is the female reproductive part and the pollen is the male reproductive part.']

List four characteristics common to all seed plants. Seed plants have roots, stems, leaves, vascular tissue, and produce seeds. Compare and contrast the characteristics of gymnosperms and angiosperms. Gymnosperms produce seeds not protected by fruit; most have needlelike, evergreen leaves.

Types of Gymnosperms All gymnosperms are found in four major divisions of plants. The divisions are Ginkgophyta, Cycadophyta, Gnetophyta, and Coniferophyta. The division Ginkgophyta contains the Ginkgo Biloba or Maidenhair tree.

Gymnosperm seeds are naked seeds, not produced in the ovary w/ one integument. Ovules become the seed. The seeds themselves rest on top of scales or w/in cones and they are exposed during fertilization. Angiosperm seeds have two integuments & produce both flowers and fruit.

About 70% of angiosperm species have endosperm cells that are polyploid. These are typically triploid (containing three sets of chromosomes), but can vary widely from diploid (2n) to 15n.

Similarities between Pteridophytes and Gymnosperms Ø In both groups, the sporophyte is differentiated into roots, stem and leaves. Ø The leaves of some gymnosperms (Eg. Cycas) and ferns show circinate vernation (=young leaves coiled inward). Ø Dichotomous venation in ferns and in some Gymnosperms (Ginkgo).

A difference between plant cells and animal cells is that most animal cells are round whereas most plant cells are rectangular. Plant cells have a rigid cell wall that surrounds the cell membrane.

Gymnosperm vs. Gymnosperms were the first plants with seeds. They are vascular plants and do not produce flowers. However, the seed is beneficial because it provides protection and food for the plant embryo. Examples of gymnosperms include conifers - or evergreens - and ginkgoes.

What are three differences between seed plants and seedless plants? Seed plants produce seeds Unlike gametophytes of seedless plants, the gametophytes of seed plants do not live independently of the sporophyte The sperm of seedless plants need water to swim to the eggs of female gametophytes.
