The directed movement of sucrose into, out of or within a cell, or between cells by means of some agent such as a transporter or pore. Sucrose is the disaccharide fructofuranosyl-glucopyranoside.

The process whose specific outcome is the progression of the embryo over time, from zygote formation to the end of seed dormancy. An example of this process is found in Arabidopsis thaliana.

A process in seed development that occurs after embryogenesis by which a quiescent state is established in a seed. Seed maturation is characterized by storage compound accumulation, acquisition of desiccation tolerance, growth arrest and the entry into a dormancy period of variable length that is broken upon germination.

The directed movement of sucrose into, out of or within a cell, or between cells by means of some agent such as a transporter or pore. Sucrose is the disaccharide fructofuranosyl-glucopyranoside.

The dehiscence of an anther to release the pollen grains contained within it.

The increase in size or mass of a seed. A seed is a propagating organ formed in the reproductive cycle of a spermatophyte, derived from the ovule and enclosing an embryo.

The directed movement of gibberellic acid across a membrane.

The directed movement of gibberellic acid across a membrane.

The process of creating protein oligomers, compounds composed of a small number, usually between three and ten, of identical component monomers. Oligomers may be formed by the polymerization of a number of monomers or the depolymerization of a large protein polymer.

The process whose specific outcome is the progression of the pollen grain over time, from its formation to the mature structure. The process begins with the meiosis of the microsporocyte to form four haploid microspores. The nucleus of each microspore then divides by mitosis to form a two-celled organism, the pollen grain, that contains a tube cell as well as a smaller generative cell. The pollen grain is surrounded by an elaborate cell wall. In some species, the generative cell immediately divides again to give a pair of sperm cells. In most flowering plants, however this division takes place later, in the tube that develops when a pollen grain germinates.

The process that occurs in a leaf near the end of its active life that is associated with the dismantling of cell components and membranes, loss of functional chloroplasts, and an overall decline in metabolism.

Any process in which callose is transported to, and/or maintained in, the cell wall. Callose is a linear 1,3-beta-d-glucan formed from UDP-glucose and is found in certain plant cell walls.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an abscisic acid stimulus.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a salicylic acid stimulus.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating an increase or decrease in the concentration of solutes outside the organism or cell.

The controlled release of a nectar by a cell or a tissue. Nectar is a fluid secreted by many angiosperms to promote pollination by providing a reward to pollinators. Nectar may also deter certain organisms from visiting or play other biological roles. Nectar is a complex solution that may include the following types of compounds: sugars, amino acids, organic acids, alkaloids, flavonoids, glycosides, vitamins, phenolics, metal ions, oils, free fatty acids, and proteins.

The dehiscence of an anther to release the pollen grains contained within it.

The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The lipid bilayer surrounding any of the compartments of the Golgi apparatus.

The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

The lipid bilayer surrounding any membrane-bounded vesicle in the cell.

The lipid bilayer surrounding any of the compartments that make up the trans-Golgi network.
