The central cell, once fertilized by a sperm cell from the pollen becomes the first cell of the endosperm, and the egg cell once fertilized become the zygote that develops into the embryo. The gap in the integuments through which the pollen tube enters to deliver sperm to the egg is called the micropyle. The stalk attaching the ovule to the ...
Apocarpus – the gynoecium consists of more than one pistil. Cell – Compound pistil – Funicle – the stalk that connects the ovule to the placenta. Funiculus – Loculus – the cavities located within a carpel, ovary, or anther. Locule – multicarpellate – Placenta – Placentation – Axile – Basal – Free-central – Pariental ...
Dicentra (Greek dís "twice", kéntron "spur"), [3] known collectively as the bleeding-hearts, is a genus containing eight species of herbaceous flowering perennial plants with unique, "heart"-shaped flowers and finely divided foliage. The species are, primarily, native to North America, although several are found in temperate East Asia.

Very small hairs or hair-like protrusions more or less confined to the margin s of an organ, as with eyelashes; in motile cells, minute, hair-like protrusions which aid ...
The pistil may be made up of one carpel or of several fused carpels (e.g. dicarpel or tricarpel), and therefore the ovary can contain part of one carpel or parts of several fused carpels. Above the ovary is the style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each ...

The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of stigmatic papillae, the cells of which are receptive to pollen ...
The secondary cell wall is a structure found in many plant cells, located between the primary cell wall and the plasma membrane. The cell starts producing the secondary cell wall after the primary cell wall is complete and the cell has stopped expanding. [ 1 ]
