The sections of the light spectrum which the âredâ and âgreenâ cones perceive overlap and this is why red and green colour vision deficiencies are often known as red/green colour blindness and why people with red and green deficiencies see the world in a similar way.
Lady Fern is easy to grow and thrive in moist, well-drained soil. Plants can tolerate dry soil conditions better than most other ferns. Lady ferns grow best in shaded areas of the garden but can handle sun if soil is constantly moist. They grow to be 1 to 3 feet high and have a plant spread of 1 to 2-1/2 feet.
Gymnosperms. Gymnosperms are one of the two groups of seed plants. The flowering plants (angiosperms), are the other. In going from mosses and ferns to the seed plants, we see a very significant difference in plant life cycles. In mosses and ferns the propagating units for new individuals are spores. major distinction we can make between seed plants (gymnosperms and angiosperms) and the non-seed plants (mosses and ferns) is that seed plants are heterosporous and non-seed plants are homosporous.
