Describe the important characteristics of gymnosperms.
Important functions of gymnosperms: 1. The time period gymnosperm refers to plant life with bare seeds (gymnos - bare, sperma - seeds), i.e., the seeds of those plant life aren't enclosed in fruits. 2. The plant-frame stages from medium to tall timber and shrubs. The massive redwood tree Sequoia is one of the tallest timber withinside the world. 3. The root device includes faucet roots. The coralloid roots found in Cycas are related to nitrogen-fixing cyanobacteria. 4. The stem may be branched (as in Pinus and Cedrus) or un-branched (as in Cycas). 5. The leaves may be simple (as in Pinus)or compound (pinnate in Cycas). The leaves are needle-like, with a thick cuticle and sunken stomata. These assist in stopping water loss. 6. Gymnosperms are heterosporous. They undergo forms of spores - microspores and megaspores. 7. Flowers are absent. The microsporophylls and megasporophylls are organized to shape compact male and lady cones. 8. Pollination takes place by and large thru wind and pollen grains attain the pollen chamber of the ovule thru the micropyle. 9. The male and woman gametophytes are depending on the sporophyte. 10. The seeds incorporate haploid endosperms and stay uncovered.
